This problem has been reported upstream, see

The Simple Search page uses the MySQL fulltext search feature. Words much match
some criteria to be found and returned, see
https://dev.mysql.com/doc/refman/5.5/en/fulltext-boolean.html. If you want to
avoid these limitations, use one of the following two solutions:

1) Use the Advanced Search page:

https://gcc.gnu.org/bugzilla/query.cgi?longdesc=-fno-ipa-icf&longdesc_type=substring&query_format=advanced&resolution=DUPLICATE


2) Type: DUPL comment:"-fno-ipa-icf" in the QuickSearch box at the top/bottom
of pages.

Note that I added DUPL (duplicate bugs only) in the query to limit the number
of bugs returned. Without it, it seems that MySQL is too slow to return data
before Apache times out.
