Searching in Code doesn't work

Whenever I use the Search function (Ctrl+F) to search for some text in my code the "Search/Replace Results" panel does not return the correct information and I cannot find a relationship between what it returned and what I asked for.  For instance, I have a function called "AppValues".  When I do a search so that I can find out where and how many times it is called it returns lines that do not include the search criteria "AppValues" and even marks those incorrect lines as locations in which to find the value.
