If search returns fewer results than the given number,
then search.cgi automatically switches from
the m=all mode (all words)
to the less strict m=any mode
(any word).
The number of results that were found in the stricter mode is available by a call for res.property("StrictModeFound") , where res is the current RESULT variable.
The default value is 0, which means don't switch automatically to a less strict mode.
