Qianfan Knowledgebase Search Skill
Search and retrieve knowledge from Baidu Qianfan platform knowledge bases. Supports semantic search, fulltext search, hybrid search, and reranking.
Workflow
- The skill executes the Python script located at
search.py - The script makes a POST request to the Qianfan Knowledgebase Search API
- The API returns structured search results with chunks, scores, and metadata
Environment Variables
| env | required | description |
|---|---|---|
| BAIDU_API_KEY | yes | Qianfan platform API Key |
| QIANFAN_KNOWLEDGEBASE_IDS | no | Knowledgebase IDs, comma-separated (used if not specified in request) |
Parameters
request body structure
| param | type | required | default | description |
|---|---|---|---|---|
| query | str | yes | Search query content | |
| knowledgebase_ids | list[str] | no | Knowledgebase ID list (uses env var if not specified) | |
| top_k | int | no | 6 | Number of chunks to return, range [1, 40] |
| score_threshold | float | no | 0.4 | Score threshold for filtering, range [0, 1] |
| enable_graph | bool | no | false | Enable knowledge graph |
| enable_expansion | bool | no | false | Return expanded chunks |
| recall | obj | no | Recall strategy configuration | |
| +recall.type | str | no | hybrid | Recall type: fulltext/semantic/hybrid |
| +recall.top_k | int | no | 100 | Recall phase top_k, range [1, 400] |
| +recall.vec_weight | float | no | 0.75 | Vector weight when type=hybrid, range [0, 1] |
| rerank | obj | no | Rerank configuration | |
| +rerank.enable | bool | no | true | Enable reranking |
| +rerank.top_n | int | no | 20 | Rerank top_n, range [1, 40] |
Note: Use flattened parameter names in input (e.g.,
recall_type,recall_top_k), the script will convert to nested structure automatically.
Example Usage
# Configure knowledgebase IDs via environment variable
export BAIDU_API_KEY="your_api_key"
export QIANFAN_KNOWLEDGEBASE_IDS="kb_id_1,kb_id_2"
python3 skills/qianfan-knowledgebase-search/search.py '{"query":"请介绍下千帆大模型知识库"}'
# Or specify knowledgebase IDs in request parameters
python3 skills/qianfan-knowledgebase-search/search.py '{"query":"如何使用API","knowledgebase_ids":["kb_id_1","kb_id_2"],"top_k":10,"recall_type":"hybrid","rerank_enable":true}'
Response Structure
Response contains the following fields:
- id: Request unique identifier
- created_at: Request timestamp
- total_count: Total number of chunks returned
- chunks: Chunk list
- chunk_id: Chunk unique identifier
- content: Chunk content (supports text/figure/table/graph types)
- rerank: Rerank score and position
- recall: Recall score and position
- meta: Metadata (chunk_type, tokens, word_count, doc_info, etc.)
- neighbors: Related chunks
Current Status
The Qianfan Knowledgebase Search skill is fully functional and can be used to retrieve knowledge from private knowledge bases on the Baidu Qianfan platform.
