I noticed the exfamily.org site search engine has apparently not yet indexed the full contents of the COG Pubs archive. I'm sure they will get around to it eventually but as a temporary solution I have indexed the exfamily.org Pubs archive using htdig ( http://www.htdig.org/ )
A fast full text search engine for the COG/TF publications archived on exfamily.org is available
This is great for research. I already used this today to compile a list of quotes of unqualified legal advice from David Berg on libel suits. It was also interesting to see how often the f-word is used in Family publications.
htdig is not the perfect solution (eventually I plan to setup something with a lot more features, bells and whistles) but it is quite fast and better than nothing.
Note: This is just an index and database. The results link to the files at exfamily.org
