Handle edge cases in search

**Feature request**
It would be great to have pagination for utils.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_pagination` with default `false`.

No file or test is named. Start by locating the utils search implementation and the configuration handling for `enable_pagination`; clarify the expected page behavior and production use cases before changing anything. Done means pagination is available when enabled and remains disabled by default, with coverage for the new behavior.
