Search
The Lens is the search bar at the top of the knowledge graph page. It is the fastest way to find content across your entire library.
Semantic and title search together
The Lens runs two searches in parallel as you type:
- Title and topic matching — instant substring match against every document title and topic tag. Matching nodes stay fully lit on the canvas; the rest recede.
- Semantic search — once your query is three or more characters, the Lens sends it to a vector search over the embedded chunks of every document in your library. Matches surface the specific passage that is most relevant, not just the document title.
The vector search uses the same embedding model (text-embedding-3-small) that was used when each document was ingested, so it finds conceptually similar content even when the exact words differ.
Reading results
Search results appear as a panel below the Lens input once semantic hits arrive. Each result shows:
- The document title and the section heading where the match was found
- A short excerpt from the matching passage
- A relevance score as a percentage
Clicking a result opens the inline document reader directly at that document. The graph canvas updates to show which nodes were matched.
The lens and the canvas
While you type, the canvas dims any node that is not matched by either the title/topic filter or the semantic search. Cluster nodes stay lit if any of their documents match. The count badge next to the Lens tells you how many nodes are currently lit.
Clear the Lens (the × button, or delete the text) to restore the full graph.
Tips
- Search by concept or question, not just keywords — the semantic layer reads the document content, so "wave-particle duality" will surface documents that discuss it even if those words do not appear in the title.
- Click a topic tag in the sidebar to set the Lens to that topic and instantly filter the graph to related documents.
- After a search, you can escalate to a synthesised answer with Ask your library — the "Ask your library" button appears in the results panel once semantic hits are available.
