This sets the minimum number of individual matches that this rule should find in order for any matches
of this rule to count. If less than this number of matches are found in the text, then none of the
matches in this rule will count. For instance if a rule searches for matches of "a" in "a a r d v a r k", and the minimum is set to 5, then no matches of "a" will be counted at all, because there are not at least
5 occurences of "a" in the text. On the other hand, if Min is set to 3 or less, then all the matches count.
The default Min value is 0.
