Some PDFs fail to be searched correctly as they appear they may contain formatting chacters internal to words. DocFetcher seems to interpret these as spaces rather than just ignoring them completely (as does, say, Google)
For example, I've attached an page from a scientific paper that I found on the web using Google (from http://cg.informatik.uni-freiburg.de/intern/seminar/87reevesShadowsWithDepthMaps.pdf) . If you try searching for, say, 'shadow map', DocFetcher returns nothing, but will give you a result if you try "s h a d o w" "m a p". This is somewhat tedious.
Any chance someone could get it to ignore (what I assume are) formatting characters?
