the default backends we ship.
PHPBB3-10323
The Fulltext_mysql class had different behavior when a dash was entered in the
search query than the fulltext_native class. Specifically, a dash was
automatically turned into boolean NOT even when the user wanted to search for
legitimate hyphenated words like farty-pants
