Searching for content in pdf files

Brand new Opus user, perhaps low on the learning curve. Surely I'm not the only one that would like to filter for *.pdf files containing a particular word (or words). I can do this with X1, but Opus obviously would offer many more choices after the files are located. Am I just missing something?

I don't think Opus has any built-in support for searching within PDF files at the moment but you could probably do it via Google Desktop which will integrate into the Opus Find utility panel, if installed. The results of your searches will end up in an Opus file collection the same as when doing a native search and Opus just queries the Google Desktop API to get the list of matching files. (No web browsers in sight, as it should be.)
