--------------------------------
Summary: 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
Reporter: Andy Webb
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/2488 adds an alwaysStopwords option that
disables the default behaviour, enabling stopwords to be always ignored.
