Optimize types for large datasets

**Description**
Currently lib lacks proper search support.

**Proposed solution**
Add configurable search with sensible defaults.

**Priority**: Low/Medium

Start by inspecting the lib directory and any existing search-related entry points; the issue names no file or test. Determine how large datasets are currently handled and where search configuration belongs. Done means configurable search exists with documented sensible defaults and coverage for the relevant behavior.
