Subject [jira] [Updated] (SOLR-3936) QueryElevationComponent: Wrong order when result grouping is activated
Date Wed, 17 Jul 2013 18:01:51 GMT

     [ https://issues.apache.org/jira/browse/SOLR-3936?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Garski updated SOLR-3936:
---------------------------------

    Attachment: SOLR-3936.patch

The root issue is that the sorting for grouped queries comes from the GroupingSpecification,
which is not modified by the QueryElevationComponent. Attached is a patch that adds support
for using query elevations with grouped queries and a corresponding unit test.

> When I use elevation together with grouping I got not the expected result order.
> I tried it with the standard solr example:
> http://localhost:8983/solr/elevate?enableElevation=true&fl=score%2C[elevated]%2Cid%2Cname&forceElevation=true&group.field=manu&group=on&indent=on&q=ipod&wt=json

> but the results ignored the elevation: 
> { 
>   "responseHeader":{ 
>     "status":0, 
>     "QTime":2, 
>     "params":{ 
>       "enableElevation":"true", 
>       "fl":"score,[elevated],id,name", 
>       "indent":"on", 
>       "q":"ipod", 
>       "forceElevation":"true", 
>       "group.field":"manu", 
>       "group":"on", 
>       "wt":"json"}}, 
>   "grouped":{ 
>     "manu":{ 
>       "matches":2, 
>       "groups":[{
