Qianfan KnowledgeBase Search

Search knowledge from Qianfan Knowledgebase. Use this when you need to retrieve information from user's private knowledge bases on Baidu Qianfan platform.

Qianfan Knowledgebase Search Skill

Search and retrieve knowledge from Baidu Qianfan platform knowledge bases. Supports semantic search, fulltext search, hybrid search, and reranking.

Workflow

1. The skill executes the Python script located at search.py
2. The script makes a POST request to the Qianfan Knowledgebase Search API
3. 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.
