Default behavior of mm has changed recently. So it is a good idea to explicitly set it to 100%. Then all of the search terms must match. > Regarding multi-word synonym, what is the best way to handle > it now?

The recommended approach for dealing with synonyms like this, is to expand the synonym when indexing..." http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.SynonymFilterFactory However index time synonyms has its own problems as well. If you add a new synonym, you need to re-index those documents that contain this newly added synonym. Also highlighting highlights whole phrases. For example you have : us, united states Searching for states will highlight both united and stated. Not sure but this seems fixed with LUCENE-3668 I was thinking to have query expansion module to handle multi-word synonyms at query time only. Either using o.a.l.search.Query manipulation or String manipulation. Similar to Lukas' posting here http://www.searchworkings.org/forum/-/message_boards/view_message/146097
