1) Check that you have configured search template to use crc-multi
with DBMode command. Note that it is "crc-multi", not "multi-crc".
2) Check queries being sent to backed using MySQL queries log.
3) You may compile search.cgi with SQL debug:
export CFLAGS=-DDEBUG_SQL
./configure <with_your_preferred_options>
make
Then put search.cgi to directory structure and check apache error_log.
All queries will be logged there.
