Add configuration options for backup

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

**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 entry point for the requested search functionality in this terminal agent. Confirm how configuration defaults are represented, then add the `enable_search` option with a default of `false`; done means the option is recognized and search behavior follows its setting.
