Handle edge cases in export

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

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

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

The issue names no files, tests, or entry points. First clarify what “search for helpers” covers and where the `enable_search` option belongs. Done should define the search behavior and expose the option with a default of `false`, but the issue does not specify how to verify either.
