Hi, If I provide a direct query\_string query as "foo bar" ( without the quotes), it gets treated as "foo" OR "bar". Is it possible to change this default behavior. I want it to be defaulted to "foo" AND "bar". Looking up at Lucene, it looks like it is configured by, [https://lucene.apache.org/core/4\_1\_0/queryparser/org/apache/lucene/queryparser/classic/QueryParserBase.html#setDefaultOperator(org.apache.lucene.queryparser.classic.QueryParser.Operator)](https://lucene.apache.org/core/4_1_0/queryparser/org/apache/lucene/queryparser/classic/QueryParserBase.html#setDefaultOperator%28org.apache.lucene.queryparser.classic.QueryParser.Operator%29) Is there a way that I can configure it when running elastic search ?? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
