Ann,
By creating a new "keyword" index (indexing the individual words in a
field/blob), we would go a long way to starting on the road of a
full-text solution (which I think of as a cross table/field index -- so
it would be a definition problem not implementation), while at the same
time providing a feature which would likely be used by a LOT of FB
users/developers.
