CIA FOIA Database with 9-11 entries

A blog entry brought to my attention the existence of a CIA database of declassified documents at http://www.foia.cia.gov/search.asp. I have begun searching through it, and thought 911blogger members may find it of some use. One must be creative in finding search terms that yield material. I found no entries, for example, under "world trade center," or "wtc," so I got out my copy of the 9-11 Commission report to get ideas, and put in Kean, which yielded an assessment of CIA performance on 9-11, dated June 2005, which I am reading through now.

Secretive

Using search term "rahman," last name of the blind sheikh, came up with a 1998 document BIN LADIN PREPARING TO HIJACK US AIRCRAFT AND OTHER ATTACKS, declassified in 2004. I don't expect this database to yield too much.
