This will always be a problem because htdig is no longer maintained, and hasn't been maintained. BUT... We can some how grab the version OpenSUSE uses as it works great there, or we work with the Strigi guys to get it implemented into KHelpCenter. This is what we are currently working on with the KDE doc/dev team with Strigi.
