Consider deprecating old routes API

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

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

**Priority**: Low/Medium

Start by locating the store and the existing routes API entry points in the repository, then review how current searches and defaults are handled. Clarify whether the goal is to deprecate old routes, add configurable search, or both; done should include agreed defaults and coverage for the resulting search behavior.
