Search plugin (I18N)

[some1]

Hello,mvlcek!

First of all, you did a great job, with all your plugins, I am really impressed.
I have one question:
Is your search plugin able to search words with some signs combinations in tags or words?
I noticed problems with search results while I am trying to put into search form combinations like that:
C#, C%, C%percent
And it finish with no result, when i cut 4 example % from the last word everything is fine.

I found regex function in your code, but to be honest i am not 100% sure if it dont get that signs.

PHP Code:

'/^(-?\d+)\s*([a-zA-Z]*)$/' 


In my honest opinion it recognize only signs a-z, A-Z, spaces, '-', and numbers. I dont see there anything about group of signs {!,@,#,$,%,^,&,*..}. Correct me if I am wrong.

Is there possibility to modify your r.extension to search word combination i mentioned upper? Of course I can try it myself, but the thing is that it might be usefull for others too.

I already tried some solution, but it works only in simulator, your function doesn't pass through it, so I've decided to ask.
