I google around and didn't find answer.

Any reasons why this property is unsupported in simple query string query?

The next step for me could be to check actual lucene code if simple query string supports that parameter...

thanks

Hi @yandooo,

the query string query in Elasticsearch uses Lucene's [`QueryParser`](https://lucene.apache.org/core/6_5_1/queryparser/org/apache/lucene/queryparser/classic/QueryParser.html) under the hood whereas the _simple_ query string query uses Lucene's [`SimpleQueryParser`](https://lucene.apache.org/core/6_5_1/queryparser/org/apache/lucene/queryparser/simple/SimpleQueryParser.html). While `QueryParser` can autogenerate phrase queries, `SimpleQueryParser` cannot. That's the reason Elasticsearch does not support this parameter.

Daniel

@danielmitterdorfer

thanks for the reply.

I see it's different hierarchy of QueryParser objects. I might need to check with Apache lucene community why it's like this.

thanks
