ActionDescription
ViewView all documents, processing status, and details
AddUpload new documents to the Knowledge Base
Enable / DisableToggle documents. Disabled documents won't be retrieved but are still stored
ArchiveArchive documents no longer frequently used
DeletePermanently delete documents from the Knowledge Base
Re-indexRe-index documents when settings are changed
### Document Status
StatusDescription
QueuingWaiting to be processed
ProcessingBeing chunked and indexed
AvailableReady for retrieval
ErrorProcessing failed — click for details
DisabledTurned off — excluded from retrieval
ArchivedArchived
💡 TIP: Use Enable/Disable instead of Delete when you want to temporarily remove documents from retrieval. You can re-enable them anytime without re-uploading. ## Manage Chunks Click on a document to view and manage its chunks: ### Chunk Actions
ActionDescription
ViewView detailed chunk content
EditModify chunk content
AddManually add a new chunk
Enable / DisableToggle individual chunks
DeleteDelete a chunk
Add ImageAttach images to a chunk
### Notes on Editing Chunks With Parent-Child Mode: · When editing a parent chunk, you can choose to regenerate its child chunks or keep them unchanged · Editing a child chunk does not update its parent chunk ⚠️ IMPORTANT: When editing chunks, new content is re-embedded automatically. However, test retrieval after editing to ensure results remain accurate. ## Best Practices ### Check Chunk Quality After creating a Knowledge Base, review chunks to identify issues: · Chunks too short — May lack sufficient context, leading to semantic loss and inaccurate answers · Chunks too long — May include irrelevant information, introducing semantic noise and lowering retrieval precision · Semantically incomplete chunks — Caused by forced chunking that cuts through sentences or paragraphs ### Use Child Chunks as Retrieval Hooks for Parent Chunks In Parent-Child mode, child chunks serve as "hooks" — retrieval entry points, after which the parent chunk provides fuller context. Effective child chunk types:

### Use Summaries to Bridge Query-Content Gaps Summaries are especially useful when: · User queries differ from document language: Add summaries in the way users actually ask questions · Concepts are implicit or buried in details: Add high-level summaries that surface core concepts · Raw text is non-textual: When a chunk is primarily code, tables, or logs — add descriptive summaries · Related chunks should be retrieved together: Apply identical summaries for grouped retrieval *📖 Previous: \[External Knowledge API]\(./07-external-knowledge-api.md) · Next: \[Metadata]\(./09-metadata.md)*
