In my cases, it can't be an accidental case.
These kind of searchs are always in the middle.
As I already say yesterday, the trailing space must be removed in records.

Yes I agree , it works for all kind of space, tab, carriage return, line feed.
But I think it's not natural for a final user which doesn't know regexp.

If we do that, we should show at the final user the meta characters he can use in the regexp.
In the filters, under the cancel and search buttons, we have some place to show that.
it can be a button near the "use regular expressions" which show some help, examples, ...
