Precision discovery

Advanced search

Build a precise query with fields, boolean operators and limiters, then run it across everything the library licenses and the repository.

Simple search
Start from a phrase
Scope, suggestions and filters work here exactly as they do on every other search box. Suggestions appear once three characters are typed; picking one adds it as a row rather than replacing the query you have built.

ANY no term yet

One blank row is the floor: the builder never renders with zero rows, and Run search stays disabled until at least one row carries a term.

— No estimate until a term is entered.
