Query_string supported features

Elastic Stack Elasticsearch

Does query_string (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/
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!
