# RAGFlow Go Version - Startup Guide

## 1. Start Dependencies

```bash
docker compose -f docker/docker-compose-base.yml up -d
```

## 2. Build Go Version RAGFlow
- First build (includes C++ dependencies and office_oxide native library):

```bash
./build.sh --cpp
```

- Subsequent builds (Go only):

```bash
./build.sh --go
```

> **Note**: If you use IDEs like GoLand to run/debug directly (via Run/Debug buttons), or run `go build` / `go run` from command line, you must set the following two CGO environment variables in your run configuration or shell:
>
> ```bash
> export CGO_CFLAGS="-I${HOME}/.office_oxide/include/office_oxide_c"
> export CGO_LDFLAGS="-L${HOME}/.office_oxide/lib -loffice_oxide -Wl,-rpath,${HOME}/.office_oxide/lib"
> ```

## 3. Run Go Version RAGFlow
Note: admin_server must be started first; otherwise, ragflow_server will encounter errors when sending heartbeats.

```bash
# Start admin server
./bin/admin_server
```

```bash
# Start RAGFlow server
./bin/ragflow_server
```
```bash
# Run CLI
./bin/ragflow-cli
```

## 4. Start Frontend
```bash
cd web && export API_PROXY_SCHEME=hybrid && npm run dev
```

## 5. Service Ports & API Routing
- ragflow_server listens on port 9384
- admin_server listens on port 9383

After updating or implementing an API, update the frontend development environment routes in web/vite.config.ts under proxySchemes.

### Proxy Schemes

| Scheme | Description |
|--------|-------------|
| `python` | All API requests from the frontend are routed to the Python server |
| `hybrid` | API requests are partially routed to the Go server and partially to the Python server |
| `go` | All API requests from the frontend are routed to the Go server |


## 6. RAGFlow commands

You can use the following CLI commands to test the corresponding API implementations.

### 6.1. Run ragflow-cli, register user, login, and logout:

```
$ ./ragflow-cli
Welcome to RAGFlow CLI
Type \? for help, \q to quit

RAGFlow(api/default)> REGISTER USER 'aaa@aaa.com' AS 'aaa' PASSWORD 'aaa';
Register successfully
RAGFlow(api/default)> login user 'aaa@aaa.com';
password for aaa@aaa.com: Password: 
Login user aaa@aaa.com successfully
RAGFlow(api/default)> logout;
SUCCESS
```

### 6.2. List currently supported providers
```
RAGFlow(api/default)> list available providers;
```

### 6.3. Add or delete a provider for the current tenant
```
RAGFlow(api/default)> add provider 'openai';
```
```
RAGFlow(api/default)> delete provider 'openai';
```
### 6.4. Create a model instance for a specific provider
```
RAGFlow(api/default)> create provider 'openai' instance 'instance_name' key 'api-key';
```

Note: The api-key is a valid API key that needs to be applied for. You can create multiple instances for the same model provider, each with a different API key.

For locally deployed models (e.g., ollama, vLLM), use the following command to add a model instance:

```
RAGFlow(api/default)> create provider 'vllm' instance 'instance_name' key '' url 'http://192.168.1.96:8123/v1';
```
### 6.5. List and delete an instance
```
RAGFlow(api/default)> list instances from 'openai';
```
```
RAGFlow(api/default)> drop instance 'instance_name' from 'openai';
```
### 6.6. List models supported by a model instance
```
RAGFlow(api/default)> list models from 'openai' 'instance_name';
```
### 6.7. Chat with LLM

- Search datasets using SQL-like dataset search syntax:
```
RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test';

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test1, test2';

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH top_k 1;

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH page 2 page_size 20;

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH similarity_threshold 0.5;

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH vector_similarity_weight 0.0;

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH keyword true;

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH use_kg true;

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH rerank_id 'BAAI/bge-reranker-v2-m3@CI@SILICONFLOW';

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH search_id 'abc123';

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH cross_languages ['Chinese'];

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH doc_ids ['doc_a', 'doc_b'];

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH meta_data_filter '{"method":"auto"}';

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH meta_data_filter '{"method":"manual","conditions":[{"key":"author","op":"eq","value":"Luo"}]}';

RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH top_k 50 similarity_threshold 0.5 vector_similarity_weight 0.5 use_kg true;
```

- Search datasets using filesystem-style search syntax:
```
RAGFlow(api/default)> search "AI"                             # search all datasets

RAGFlow(api/default)> search "AI" datasets/test               # search only dataset 'test'

RAGFlow(api/default)> search "AI" datasets/test -n 20         # return top 20 results

RAGFlow(api/default)> search "AI" datasets 'test1' 'test2'    # search in datasets
```

> [!Note]
>  - `search` is the simple filesystem search command and only accepts `query [path] [-n number]`.
>  - `RETRIEVE` / `SEARCH ... ON DATASETS ...` is the SQL-like search command and supports full `WITH` option expansion.
>  - `WITH` options include: `top_k`, `page_size`, `page`, `similarity_threshold`, `vector_similarity_weight`, `keyword`, `use_kg`, `rerank_id`, `search_id`, `cross_languages`, `doc_ids`, and `meta_data_filter`.
  - Example with multiple options:
```
RAGFlow(api/default)> RETRIEVE 'AI' ON DATASETS 'test' WITH top_k 50 similarity_threshold 0.5 vector_similarity_weight 0.5 use_kg true;
```
