Reasonably modern linux box, Core i5. Both the xapian db and the mail
files are on the same 7200 RPM SATA drive, ext4 filesystem.

I guess the SSD might explain why you your uncached results are not as
bad as mine.

My test search matches 8800 messages grouped into 5550 threads.

Wit the patch cached results go from 2.5 secs to 1.5, uncached goes from
40 secs to 6.

Thanks for the clue on the missing subject lines, your change does
indeed fix the problem!
