Problem searching in AX 2009.

Hello.

I am using AX 2009.

There is a problem on a specific environment, when doing search a specific string in whole aot, when searching strings

(I dont know if it is the searched string problem, because it is like vendtable.insert()- with a dot inside). 

The search ends too fast (couple of seconds), and the result of search is empty (even I know for sure that the search string exists).

Thanks :)
