SOLR-17959: Add alwaysStopwords option to edismax (#3802)
> Add alwaysStopwords option to edismax
> -------------------------------------

> Key: SOLR-17959
> URL: https://issues.apache.org/jira/browse/SOLR-17959
> Project: Solr
> Issue Type: Improvement
> Components: query parsers

> We were surprised by edismax's behaviour for pure-stopword queries, having
> expected that these would return zero results. Its 'If a query consists of
> all stopwords, such as "to be or not to be", then all words are required.'
> behaviour is the opposite to what we want as we're using query-time stopwords
> to prevent particular query terms matching, but there's no way to disable the
> behaviour other than using dismax instead, which may have other impacts.
> https://github.com/apache/solr/pull/3802 adds an alwaysStopwords option that
> disables the default behaviour, enabling stopwords to be always ignored.
