I still think this is one of the best ideas that someone has come up with in years.
In many ways it would be used in most queries if anyone wanted to look at the field indexes or the query parsed and get better results. Maybe people are not talking about it because mm=1, mm=0 is still overly confusing? This got me thinking - why not add mm in the solrconfig.xml in the pipeline for a Field Type? Similar to WhitespaceTokenizer? We could call it "MustMatch" and set a minimum, maximum and words... Then we could set it on the index, or query side as needed... ? Thoughts?
