Windows search shows all files with searching file extension

Question

I need to search for file wx.h in in directory and all subdirectoryes. I just write filename in search box and press enter. On output I have many files with extension .h. Why? I was not asking for other files. How to ask windows to find exactly what I wont?

Answer 1

By only putting in .h in your search it's going to give you any and all files with .h included. If your file is wx.h, then use that as your search term.
