I am having the same kind of difficulty. Slow returns on results.
It may be bad database architecture or implementation (perhaps both),
but I need to be able to pick out text fragments . . . like %value%.
I understand that indexes do not help with "LIKE %value%" queries, is
there anything else that I can do to speed up the return on results.
Thanks,
Brett

Having 27 indexes and using queries with LIKE "%...%" is a nice
recepee for slowness.
Try normalising your schema and using fulltext search instead of LIKE
"%...%". "%..%" queries can't use indices.
