Add functions to modify a search expression (#8293)

* Allows easier modifications of the search expression.
* Add proper `__toString()` instead of just returning the raw input string. Allows in particular showing the result of the actual parsing of the raw input string in the UI.

Needed for https://github.com/FreshRSS/FreshRSS/pull/8294
