Cetin,
I don't have XP to test, but I sure feel your pain. I use the windows search tool all the time and couldn't be without it. While I don't have an answer, I found a couple of links that may give you some ideas:

It seems that the search companion uses indexes to find files. Could it be a problem with the search index?

>How do you search for a file that you know extension of file that contains known word(s) ? IOW what does 'A word or a phrase in the file:' exactly mean ?
>If I have a file named 'myfile.prg' with 'SQLExec(' in it :
>Filename : myfile
>Finds that one along with others.
>Filename : myfile
>A word or a phrase in the file: SQLExec
>or %SQLExec%, *SQLExec*, [SQLExec], "SQLExec"
>fails. What is the trick ? Could anyone made this work in XP ?
>PS: Not talking about VFP filer nor coding myself only winkey+F.
