Why not store them in separate columns? You could then have the domain
field be a foreign key into another table.

Hi Sheeri
No, I wanted to search through both columns in the same time (and it
will be always at the same time) - the problem was I didn't know that I
have to have one multi-column index.

But, it's fixed (after really helpful comments on this mailing list) and
works perfect

Have you tried the following:
1) ordering by only part.d and seeing how long the query takes
2) putting an index on (part.d, cwGroup.stripped_cw) and seeing how
long the query takes.
1 will help pinpoint the problem, and 2 might actually help.

I agree, you may want to look at adding another card and disks, for
speed and to segregate the various operations (temp, logging, data).
Splitting up your MYD and MYI files may help, though if you have enough
RAM to keep indexes in memory, maybe you don't need to do that.

On your 3rd question, about how to make things faster:
More RAM should help by allowing the server to keep more/all of the
