Don, You found only 165 ESTs that mention "BLAST" in the comment field???

I believe that virtually all ESTs are BLAST searched before being
submitted to the database, and I have heard a statistic that about 40% of
them find one or more significant hits.  You should get hundred of
thousands of hits, no?
Where is this information stored if it is not in the comment or
description fields??
