Using a PDF file: From the many PowerPoint files, it used to be possible to write out a single PDF file that was convenient to search. However, with the latest versions of PowerPoint, the size of the created PDF is so large that we have had to write out several smaller PDF files, requiring multiple searches instead of a single search.

Using Windows7 Folder Search:
By putting all the files in a single folder, it is possible to use folder search which restricts the search to what is in that folder. What is returned is a list of clickable files; that is, I know what file contains the 'hit', but I don't know 'where' until I open the file and look.

What I am looking for:
A single search, restricted to a set of a few dozen files, that returns the files containing the string, AND enough context that I can see what edits are necessary.

Perhaps I have already found the best methods and should stop looking?

Thanks,
Rob
