I turned off compression (and sorting) and let my program run overnight. I
ended up with 37,723 master records (e-mail) and 51,581 related records (the
e-mail text). Searching for e-mail by it's text now takes about a second.

In other words, without compression, my program was able to add almost twice
as many records in the same time frame and searches take almost no time at
all, not the 2-minutes I saw earlier.

That it takes longer to add records is to be expected, and I don't mind. But
the compression seems to be interfering with the searches.

As a next step, I am going to turn compression back on but turn off sorting
and add records again. I just want to make sure that the problem with
searching was due to compression and not the sorting bug I reported
yesterday.
