I have recently purchased the commercial version with the PDF plugin. I'm trying to get it to search MS Word docs as well and have place the appropiate lines into the gw command, but still no luck. It is searching PDF's just fine though. Here is my .set file.
# handle PDF files with purchased PDF plugin
napplication/pdf,pdf,pdftotx
napplication/msword,doc,pdftotx
# allow big files so PDF doesn't get truncated
