There is still a difference depending on which kind of search you do.
If I search for all of my posts mentioning valgrind, using the "search single content type" option, then it all works well.
But if I select just posts in search multiple content types, it comes up empty.
Even checking the "all types" check-box doesn't help.
One further thing, this error message appeared once, just after one of my search tests.
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 8 bytes) in /home/cprogram/public_html/cboard/includes/functions.php on line 1206
