If a naive user enters a string that contains typical stopwords like "and" and "the", these seem to be included in the word count for the must match criteria of the the dismax query.
So, if for example the mm parameter is the default " 2>-1 5>-2 6>90%" and the user enters something like "Jason and the Argonauts", this won't match a document with that title because the word count is treated as 4 and only 2 words match. As the dismax query is recommended for naive users, wouldn't be more logical to apply the mm criteria after applying the stopword filter on the query? Steven H.
