Does query\_string ([http://www.elasticsearch.org/guide/reference/query-](http://www.elasticsearch.org/guide/reference/query-) dsl/query-string-query.html) support all lucene features (http:// [lucene.apache.org/core/old\_versioned\_docs/versions/3\_0\_0/](http://lucene.apache.org/core/old_versioned_docs/versions/3_0_0/) queryparsersyntax.html), like: proximity searching, boosting a term, boolean operators, grouping, field searching, etc ? Is there a way to disable/enable some of these (I see for wildcard there is, but do not see for any other feature) Thanks! ---

Yes, it uses the same parser, with some extensions (like automatically using the relevant analyzer for a specific field, supporting multiple fields).

Thanks! I have 2 related follow-up questions: 1. I am unable to search for query string's with two question mark ( ? ) wildcard character together. For ex: "h?l?o" works fine, but "he??o" fails to work (ES returns HTTP 500). 2. Is there some place where I can find exact format for valid query string's so that I can parse it on front-end, and user cannot enter invalid strings, like for example these query\_string's fail (ES returns HTTP 500): "hello AND", "hello +", "hello OR", "hello~~", "hello~1.0", "hel??o", "hello:", etc ... Failure of most of these make sense, but is there a proper query string language defined, so that I can verify user input with confidence ? Thanks!
