Description

If the JSON Query DSL is used (POSTing JSON), it requires that the default "lucene" query parser is used. If for some reason defType is set, like in the defaults section of the request handler, then this doesn't work. Internally, the JSON is rewritten to local-params syntax which requires the default parser, not another like edismax.

This behavior broke in 7.2 when other parsers stopped processing local-params in the name of security.
