Currently, e-commerce retail platforms extensively use intelligent customer service systems to manage a wide range of user enquiries. However, traditional intelligent customer service often struggles to meet users’ increasingly complex and varied needs. For example, customers may require detailed comparisons of functionalities between different product models before making a purchase; they might be unable to use certain features due to losing the instruction manual; or, in the case of home products, they may need to arrange an on-site installation appointment through customer service.

To address these challenges, we have identified several common demand scenarios, including queries about functional differences between product models, requests for usage assistance, and scheduling of on-site installation services. Building on the recently launched Agent framework of RAGFlow, this blog presents an approach for the automatic identification and branch-specific handling of user enquiries, achieved by integrating workflow orchestration with large language models.

The workflow is orchestrated as follows:

The following sections offer a detailed explanation of the implementation process for this solution.

1. Prepare datasets​

1.1 Create datasets​

You can download the sample datasets from Hugging Face Datasets.

Create the "Product Information" and "User Guide" knowledge bases and upload the relevant dataset documents.

1.2 Parse documents​

For documents in the 'Product Information' and 'User Guide' knowledge bases, we choose to use Manual chunking.

Product manuals are often richly illustrated with a combination of text and images, containing extensive information and complex structures. Relying solely on text length for segmentation risks compromising the integrity of the content. RAGFlow assumes such documents follow a hierarchical structure and therefore uses the "smallest heading" as the basic unit of segmentation, ensuring each section of text and its accompanying graphics remain intact within a single chunk. A preview of the user manual following segmentation is shown below:

2. Build workflow​

2.1 Create an app​

Upon successful creation, the system will automatically generate a Begin component on the canvas.

In the Begin component, the opening greeting message for customer service can be configured, for example:

Hi! I'm your assistant. 

2.2 Add a Categorize component​

The Categorize component uses a Large Language Model (LLM) for intent recognition. It classifies user inputs and routes them to the appropriate processing workflows based on the category’s name, description, and provided examples.

2.3 Build a product feature comparison workflow​

The Retrieval component connects to the "Product Information" knowledge base to fetch content relevant to the user’s query, which is then passed to the Agent component to generate a response.

Add a Retrieval component named "Feature Comparison Knowledge Base" and link it to the "Product Information" knowledge base.

Add an Agent component after the Retrieval component, name it "Feature Comparison Agent," and configure the System Prompt as follows:

## Role
You are a product specification comparison assistant.
## Goal
Help the user compare two or more products based on their features and specifications. Provide clear, accurate, and concise comparisons to assist the user in making an informed decision.
---
## Instructions
- Start by confirming the product models or options the user wants to compare.
- If the user has not specified the models, politely ask for them.
- Present the comparison in a structured way (e.g., bullet points or a table format if supported).
- Highlight key differences such as size, capacity, performance, energy efficiency, and price if available.
- Maintain a neutral and professional tone without suggesting unnecessary upselling.
---

Configure User prompt

User's query is /(Begin Input) sys.query 

Schema is /(Feature Comparison Knowledge Base) formalized_content

After configuring the Agent component, the result is as follows:

2.4 Build a product user guide workflow​

The Retrieval component queries the "User Guide" knowledge base for content relevant to the user’s question, then passes the results to the Agent component to formulate a response.

Add a Retrieval component named "Usage Guide Knowledge Base" and link it to the "User Guide" knowledge base.

Add an Agent component after the Retrieval component, name it "Usage Guide Agent," and configure its System Prompt as follows:

## Role
You are a product usage guide assistant.
## Goal
Provide clear, step-by-step instructions to help the user set up, operate, and maintain their product. Answer questions about functions, settings, and troubleshooting.
---
## Instructions
- If the user asks about setup, provide easy-to-follow installation or configuration steps.
- If the user asks about a feature, explain its purpose and how to activate it.
- For troubleshooting, suggest common solutions first, then guide through advanced checks if needed.
- Keep the response simple, clear, and actionable for a non-technical user.
---

Write user prompt

User's query is /(Begin Input) sys.query 

Schema is / (Usage Guide Knowledge Base) formalized_content

After configuring the Agent component, the result is as follows:

2.5 Build an installation booking assistant​

The Agent engages in a multi-turn dialogue with the user to collect three key pieces of information: contact number, installation time, and installation address. Create an Agent component named "Installation Booking Agent" and configure its System Prompt as follows:

# Role
You are an Installation Booking Assistant.
## Goal
Collect the following three pieces of information from the user 
1. Contact Number  
2. Preferred Installation Time  
3. Installation Address  
Once all three are collected, confirm the information and inform the user that a technician will contact them later by phone.
## Instructions
1. **Check if all three details** (Contact Number, Preferred Installation Time, Installation Address) have been provided.
2. **If some details are missing**, acknowledge the ones provided and only ask for the missing information.
3. Do **not repeat** the full request once some details are already known.
4. Once all three details are collected, summarize and confirm them with the user.

Write user prompt

User's query is /(Begin Input) sys.query 

After configuring the Agent component, the result is as follows:

If user information needs to be registered, an HTTP Request component can be connected after the Agent component to transmit the data to platforms such as Google Sheets or Notion. Developers may implement this according to their specific requirements; this blog article does not cover implementation details.

2.6 Add a reply message component​

For these three workflows, a single Message component is used to receive the output from the Agent components, which then displays the processed results to the user.

2.7 Save and test​

Click Save → Run → View Execution Result. When inquiring about product models and features, the system correctly returns a comparison:

When asked about usage instructions, the system provides accurate guidance:

When scheduling an installation, the system collects and confirms all necessary information:

Summary​

This use case can also be implemented using an Agent-based workflow, which offers the advantage of flexibly handling complex problems. However, since Agents actively engage in planning and reflection, they often significantly increase response times, leading to a diminished customer experience. As such, this approach is not well suited to scenarios like e-commerce after-sales customer service, where high responsiveness and relatively straightforward tasks are required. For applications involving complex issues, we have previously shared the Deep Research multi-agent framework. Related templates are available in our template library.

The customer service workflow presented in this article is designed for e-commerce, yet this domain offers many more scenarios suitable for workflow automation—such as user review analysis and personalized email campaigns—which have not been covered here. By following the practical guidelines provided, you can also easily adapt this approach to other customer service contexts. We encourage you to build such applications using RAGFlow. Reinventing customer service with large language models moves support beyond “mechanical responses,” elevating capabilities from mere “retrieval and matching” to “cognitive reasoning.” Through deep understanding and real-time knowledge generation, it delivers an unprecedented experience that truly “understands human language,” thereby redefining the upper limits of intelligent service and transforming support into a core value engine for businesses.

Workflow overview​

This tutorial shows how to create a SQL Assistant workflow that enables natural language queries for SQL databases. Non-technical users like marketers and product managers can use this tool to query business data independently, reducing the need for data analysts. It can also serve as a teaching aid for SQL in schools and coding courses. The finished workflow operates as follows:

The database schema, field descriptions, and SQL examples are stored as knowledge bases in RAGFlow. Upon user queries, the system retrieves relevant information from these sources and passes it to an Agent, which generates SQL statements. These statements are then executed by a SQL Executor component to return the query results.

Procedure​

1. Create three knowledge bases​

1.1 Prepare dataset files​

You can download the sample datasets from Hugging Face Datasets.

The following are the predefined example files:

1. Schema.txt

CREATE TABLE `users` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(50) NOT NULL,
  `password` VARCHAR(50) NOT NULL,
  `email` VARCHAR(100),
  `mobile` VARCHAR(20),
  `create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  UNIQUE KEY `uk_username` (`username`),
  UNIQUE KEY `uk_email` (`email`),
  UNIQUE KEY `uk_mobile` (`mobile`)
);

...

Note: When defining schema fields, avoid special characters such as underscores, as they can cause errors in SQL statements generated by the LLM. 2. Question to SQL.csv

What are the names of all the Cities in Canada
SELECT geo_name, id FROM data_commons_public_data.cybersyn.geo_index WHERE iso_name ilike '%can%

What is average Fertility Rate measure of Canada in 2002 ?
SELECT variable_name, avg(value) as average_fertility_rate FROM   data_commons_public_data.cybersyn.timeseries WHERE variable_name = 'Fertility Rate' and geo_id = 'country/CAN' and date >= '2002-01-01' and date < '2003-01-01' GROUP BY 1;

What 5 countries have the highest life expectancy ?
SELECT geo_name, value FROM data_commons_public_data.cybersyn.timeseries join data_commons_public_data.cybersyn.geo_index ON timeseries.geo_id = geo_index.id WHERE  variable_name = 'Life Expectancy' and date = '2020-01-01' ORDER BY value desc limit 5;


...

3. Database Description EN.txt

### Users Table (users)
The users table stores user information for the website or application. Below are the definitions of each column in this table:
- `id`: INTEGER, an auto-incrementing field that uniquely identifies each user (primary key). It automatically increases with every new user added, guaranteeing a distinct ID for every user.
- `username`: VARCHAR, stores the user’s login name; this value is typically the unique identifier used during authentication.
- `password`: VARCHAR, holds the user’s password; for security, the value must be encrypted (hashed) before persistence.
- `email`: VARCHAR, stores the user’s e-mail address; it can serve as an alternate login credential and is used for notifications or password-reset flows.
- `mobile`: VARCHAR, stores the user’s mobile phone number; it can be used for login, receiving SMS notifications, or identity verification.
- `create_time`: TIMESTAMP, records the timestamp when the user account was created; defaults to the current timestamp.
- `update_time`: TIMESTAMP, records the timestamp of the last update to the user’s information; automatically refreshed to the current timestamp on every update.

...

1.2 Create knowledge bases in RAGFlow​

Schema knowledge base

Create a knowledge base titled "Schema" and upload the file Schema.txt.

Tables in the database vary in length, each ending with a semicolon (;).

CREATE TABLE `users` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(50) NOT NULL,
  `password` VARCHAR(50) NOT NULL,
  ...
  UNIQUE KEY `uk_mobile` (`mobile`)
);

CREATE TABLE `products` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(100) NOT NULL,
  `description` TEXT,
  `price` DECIMAL(10, 2) NOT NULL,
  `stock` INT NOT NULL,
  ...
  FOREIGN KEY (`merchant_id`) REFERENCES `merchants` (`id`)
);

CREATE TABLE `merchants` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(100) NOT NULL,
  `description` TEXT,
  `email` VARCHAR(100),
  ...
  UNIQUE KEY `uk_mobile` (`mobile`)
);

To isolate each table as a standalone chunk without overlapping content, configure the knowledge base parameters as follows:

• Chunking Method: General
• Chunk Size: 2 tokens (minimum size for isolation)
• Delimiter: Semicolon (;) RAGFlow will then parse and generate chunks according to this workflow:

Below is a preview of the parsed results from Schema.txt:

We now validate the retrieved results through retrieval testing:

Question to SQL knowledge base

Create a new knowledge base titled "Question to SQL" and upload the file "Question to SQL.csv".

Set the chunking method to Q&A, then parse Question_to_SQL.csv to preview the results.

We now validate the retrieved results through retrieval testing:

Database Description knowledge base Create a new knowledge base titled "Database Description" and upload the file "Database_Description_EN.txt".

Configuration (Same as Schema Knowledge Base):

• Chunking Method: General
• Chunk Size: 2 tokens (minimum size for isolation)
• Delimiter: Semicolon ### Below is a preview of the parsed Database_Description_EN.txt following configuration.

We now validate the retrieved results through retrieval testing:

Note: The three knowledge bases are maintained and queried separately. The Agent component consolidates results from all sources before producing outputs."

2. Orchestrate the workflow​

2.1 Create a workflow application​

Once created successfully, the Begin component automatically appears on the canvas.

You can configure a welcome message in the Begin component. For example:

Hi! I'm your SQL assistant, what can I do for you?

2.2 Configure three Retrieval components​

Add three parallel Retrieval components after the Begin component, named as follows:

• Schema
• Question to SQL
• Database Description Configure each Retrieval component:

1. Query variable: sys.query
2. Knowledge base selection: Select the knowledge base whose name matches the current component's name.

2.3 Configure the Agent component​

Add an Agent component named 'SQL Generator' after the Retrieval components, connecting all three to it.

Write System Prompt:

### ROLE
You are a Text-to-SQL assistant.  
Given a relational database schema and a natural-language request, you must produce a **single, syntactically-correct MySQL query** that answers the request.  
Return **nothing except the SQL statement itself**—no code fences, no commentary, no explanations, no comments, no trailing semicolon if not required.

### EXAMPLES  
-- Example 1  
User: List every product name and its unit price.  
SQL:
SELECT name, unit_price FROM Products;

-- Example 2  
User: Show the names and emails of customers who placed orders in January 2025.  
SQL:
SELECT DISTINCT c.name, c.email
FROM Customers c
JOIN Orders o ON o.customer_id = c.id
WHERE o.order_date BETWEEN '2025-01-01' AND '2025-01-31';

-- Example 3  
User: How many orders have a status of "Completed" for each month in 2024?  
SQL:
SELECT DATE_FORMAT(order_date, '%Y-%m') AS month,
       COUNT(*) AS completed_orders
FROM Orders
WHERE status = 'Completed'
  AND YEAR(order_date) = 2024
GROUP BY month
ORDER BY month;

-- Example 4  
User: Which products generated at least \$10 000 in total revenue?  
SQL:
SELECT p.id, p.name, SUM(oi.quantity * oi.unit_price) AS revenue
FROM Products p
JOIN OrderItems oi ON oi.product_id = p.id
GROUP BY p.id, p.name
HAVING revenue >= 10000
ORDER BY revenue DESC;

### OUTPUT GUIDELINES
1. Think through the schema and the request.  
2. Write **only** the final MySQL query.  
3. Do **not** wrap the query in back-ticks or markdown fences.  
4. Do **not** add explanations, comments, or additional text—just the SQL.

Write User Prompt:

User's query: /(Begin Input) sys.query  
Schema: /(Schema) formalized_content  
Samples about question to SQL: /(Question to SQL) formalized_content  
Description about meanings of tables and files: /(Database Description) formalized_content

After inserting variables, the populated result appears as follows:

2.4 Configure the ExeSQL component​

Append an ExeSQL component named "SQL Executor" after the SQL Generator.

Configure the database for the SQL Executor component, specifying that its Query input comes from the output of the SQL Generator.

2.5 Configure the Message component​

Append a Message component to the SQL Executor.

Insert variables into the Messages field to enable the message component to display the output of the SQL Executor (formalized_content):

2.6 Save and test​

Click Save → Run → Enter a natural language question → View execution results.

Finale​

Finally, like current Copilot technologies, NL2SQL cannot achieve complete accuracy. For standardized processing of structured data, we recommend consolidating its operations to specific APIs, then encapsulating these APIs as MCPs (Managed Content Packages) for RAGFlow. We will demonstrate this approach in a forthcoming blog.

Deep Research: The defining capability of the Agent era​

The year 2025 is hailed as the dawn of Agent adoption. Among the many unlocked possibilities, Deep Research—and the applications built upon it—stands out as especially significant. Why is this? Using Agentic RAG and its reflection mechanism, Deep Research enables large language models to reason deeply with users’ proprietary data. This is key for Agents to tackle more advanced tasks. For example, whether helping with creative writing or aiding decision-making in different industries, these rely on Deep Research. Deep Research represents a natural step forward from RAG, improved by Agents. Unlike basic RAG, it explores data at a deeper level. Like RAG, it can work on its own or serve as the base for other industry-specific Agents. A Deep Research workflow typically follows this sequence:

1. Decomposition & Planning: The large language model breaks down the user’s query and devises a plan.
2. Multi-Source Retrieval: The query is sent to multiple data sources, including internal RAG and external web searches.
3. Reflection & Refinement: The model reviews the retrieved information, reflects on it, summarizes key points, and adjusts the plan as needed.
4. Iteration & Output: After several iterations, a data-specific chain of thought is formed to generate the final answer or report.

Built-in Deep Research was already implemented in RAGFlow v0.18.0. Although at that stage it primarily served as a demo to validate and explore deep reasoning’s potential in enterprise settings. Across the industry, Deep Research implementations generally fall into two categories:

• No-Code Workflow Orchestration: Using a visual workflow interface with predefined workflows to implement Deep Research.
• Dedicated Agent Libraries or Frameworks: Many current solutions follow this approach (see [Reference 1] for details).

RAGFlow 0.20.0, a unified RAG and Agent engine supporting both Workflow and Agentic modes with seamless orchestration on a single canvas, can implement Deep Research through either approach. However, employing Workflow for Deep Research is only functional, as its interface appears like this:

This gives rise to two main problems:

1. Overly Complex and Unintuitive Orchestration: If the basic Deep Research template is already this complicated, a full application would become a tangled web of workflows that are hard to maintain and expand.
2. Better Suited to Agentic Methods: Deep Research naturally relies on dynamic problem breakdown and decision-making, with control steps driven by algorithms. Workflow drag-and-drop interfaces only handle simple loops, lacking the flexibility needed for advanced control.

RAGFlow 0.20.0 offers a comprehensive Agent engine designed to help enterprises build production-ready Agents using no-code tools. As the key Agent template, Deep Research strikes a careful balance between simplicity and flexibility. Compared to other solutions, RAGFlow highlights these strengths:

• Agentic Execution, No-Code Driven: A fully customisable application template—not just an SDK or runtime—that uses Agentic mechanisms while remaining easy to access through a no-code platform.
• Human Intervention (Coming Soon): Although Deep Research depends on LLM-generated plans, which can feel like a black box, RAGFlow’s template will support manual oversight to introduce certainty—a vital feature for enterprise-grade Agents.
• Business-Focused and Outcome-Oriented:

Developers can customise the Deep Research Agent’s structure and tools, such as configuring internal knowledge bases for enterprise data retrieval, to meet specific business needs. Full transparency in the Agent’s workflow—including its plans and execution results—allows timely optimisation based on clear, actionable insights.

Practical Guide to Setting Up Deep Research​

We use a Multi-Agent architecture [Reference 2], carefully defining each Agent’s role and responsibilities through thorough Prompt Engineering [Reference 4] and task decomposition principles [Reference 6]:

• Lead Agent: Coordinates the Deep Research Agent, handling task planning, reflection, and delegating to Subagents, while keeping track of all workflow progress.
• Web Search Specialist Subagent: Acts as the information retrieval expert, querying search engines, assessing results, and returning URLs of the best-quality sources.
• Deep Content Reader Subagent: Extracts and organises web content from the URLs provided by the Search Specialist, preparing refined material for report drafting.
• Research Synthesizer Subagent: Generates professional, consultancy-grade deep-dive reports according to the Lead Agent’s instructions.

Model selection​

• Lead Agent: Prioritizes models with strong reasoning capabilities, such as DeepSeek-R1, Qwen-3, Kimi-2, ChatGPT-o3, Claude-4, or Gemini-2.5 Pro.
• Subagents: Optimized for execution efficiency and quality, balancing reasoning speed with output reliability. Context window length is also a key criterion based on their specific roles.

Temperature setting​

Given the fact-driven nature of this application, we set the temperature parameter to 0.1 across all models to ensure deterministic, grounded outputs.

Upcoming versions​

The current RAGFlow 0.20.0 release does not yet support human intervention in Deep Research execution, but this feature is planned for future updates. It is crucial for making Deep Research production-ready, as it adds certainty and improves accuracy [Reference 5] to what would otherwise be uncertain automated processes. Manual oversight will be vital for enterprise-grade Deep Research applications.

We warmly invite everyone to stay tuned and star RAGFlow at https://github.com/infiniflow/ragflow
