I think something like this should do the trick. Without overriding anything.


Query query= QueryParser.parse("User Entered String");

if (query instanceof BooleanQuery)
((BooleanQuery)query).setMinimumNumberShouldMatch(3);

You can steal code from solr too, ( e.g. how to calculate mm and optional clause count etc.)
