## Search knowledge
1. Open the Knowledge tab in the intended base and search with a material ID or short project keyword.
2. Read the entry, tags and source references.
3. Open the accessible original and confirm the cited location and document revision.
4. If you need synthesis across entries, give the configured model an explicit scope.
Local full-text search does not require an online model. Model synthesis and online collection require their connections.
## Edit and restore
Edit an entry's title, body or tags and save to create a revision. Before using an available rollback action, inspect the content to be restored. Revisions are not a replacement for source-file or whole-library backups.
## What does a graph mean?
The graph displays relationships between notes and supports zoom and fit-to-view. Review and adjust automatically suggested similarities. A relationship does not mean a conclusion is approved or that product specifications, prices or brands match.
## Import and export
Versioned knowledge packages support exchange. Inspect additions, conflicts and drafts before importing; do not assume every item will be overwritten. An exchange package is not a complete backup of source files and configuration.
## If search finds nothing
Check the selected base, permissions, draft status and parsing result, then shorten the query. Try the source filename, note title and words from its body as separate clues.
