Quicksearch for exact term - how?

[SkyFrontier]

Hello.
I'm trying to perfom

text quicksearch("<curbase> /nfcw /fuzzy=0"); //non recursive, files only, case-sensitive
w = whole words, not supported here?
fuzzy 0 = 'Value 0 is equivalent to non-fuzzy so it's the same as omitting the whole switch.' Isn't this equivalent to whole word?

-anyway, "whole words" won't do a difference for what I want...

desired: "This.Is" matches "This.Is.txt" but not "This.is.doc" neither "1 - This.Is.txt"

On the other hand, how could I achieve the same suing a regex search?
text quicksearch(">(\<curbase>)");

text quicksearch(">.*(\<curbase>)$"); //returns empty

Thanks.

Huh?

Can you somehow purify the presentation of the problem?
