When using the search bar, usually the last settings of the S/R dialogue are used.
In general this makes sense, but sometimes the S/R dialogue has Whole words or Match case activated. This can limit the search results without that the user really is aware of this. This can lead to ugly mistakes.
Wouldn't one of the following points make sense:
I think the first option would keep the UI quite tidy.
If I remember correctly, much of the functionality you wish for the search bar, used to be present.
