Semantic retrieval index FAQ
How do I choose between Local Document and Business Object?
- Choose Local Document when enterprise knowledge is maintained as PPT, Excel, or PDF files.
- Choose Business Object when you want Q&A over system business data, or when knowledge already lives in system objects.
How should I pick a title field?
Choose a field with business meaning that users query most often. During retrieval, the title field is a separate recall path that is reranked with semantic and full-text results to produce the answer.
How do I improve recall accuracy?
- Check whether the title and chunk fields have business meaning.
- Adjust the segmentation rules for the content field and preview chunks to confirm the split is reasonable.
- For document indexes, use document hierarchy to improve recall and precision.
Where can I use a built index?
- Insert a Semantic Retrieval Index variable in a prompt template.
- Add a RAG knowledge base operation in the Agent Operation Library and link it to the index.
