Hi Mark,

I do not use MySQL here, but the table that is to be indexed can be
very large and I certainly would not want to wait for a myisamchk to
complete after a crash. The sphinx option is the only viable one for
use with mysql. Moving to PostgreSQL would work but as suggested by
others, if your expertise is with MySQL, stick with MySQL.
