One of the new features introduced with DEVONagent 3.0 is the ability to not only search HTML pages and news feeds but also PDF, PostScript, OpenOffice, Oracle Open Office, and Microsoft Word documents. To make DEVONagent search also these other document types, expand the search window, switch to the Settings tab, and select the file types you want to search in the Files: area. Then run your search. PDF and other documents show a little file type icon in the Results list.
Alternatively, you can, of course, also edit your most often used search sets and switch them on there, too.
