I have a situation similar to the one described in this thread Stopword with Query_string. In ES 2.4, the query_string worked perfectly with stopwords, if we properly specified the analyzer in query time.
However, after upgrading to ES 5.1, that problem occurs, even if I specify the analyzer during query time. The query_string doesn't find documents if the query term contains any stopword.
Does anybody know if there is a change in query_string concerning stopwords from 2.4 version to 5.1?
Thanks in advance,
