Optimize lib for large datasets

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

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

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

Start by locating the configuration handling and the utils-related search entry point; the issue does not name files or tests. Check how options are defined and consumed, then determine the expected behavior for `enable_search` being false by default. Done should include the option and working search behavior for the stated production use case, with relevant tests if the project has them.
