How is it supposed to do a full-text search without looking at every
record, pray tell?
This is a case where if you want to do this type of search on
a database, you should have a coordinated search qualifying it
with an mv_column_op of eq to limit the initial select. (Your
current mv_column_op is right now an mv_noop, as mv_column_op
only applies in coordinated search mode.
Another thing you can do is pass the search spec to your own
custom query on the results page.
This should be discussed in a posting on the mail list -- perhaps we
can gen up an example in the new docs.
