Subject [jira] [Created] (SOLR-4197) EDismax allows end users to use local params in q= to override global params

Peter Wolanin created SOLR-4197:
-----------------------------------

             Summary: EDismax allows end users to use local params in q= to override global
params
                 Key: SOLR-4197
                 URL: https://issues.apache.org/jira/browse/SOLR-4197
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.0, 3.6, 3.5
            Reporter: Peter Wolanin



Edismax is advertised as suitable to be used to "process advanced user input directly".  Thus,
it would seem reasonable to have an application directly pass user input in the q= parameter
to a back-end Solr server.

However, it seems that users can enter local params at the start of q= which override the
global params that the application (e.g. website) may have set on the query string.  Confirmed
with Erik Hatcher that this is somewhat unexpected behavior (though one could argue it's an
expected feature of any query parser)

Proposed fix - add a parameter (e.g. that can be used as an invariant) that can be passed
to inhibit Solr from using local params from the q= parameter.

This is somewhat related to SOLR-1687
