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":[{
> "groupValue":"belkin",
> "doclist":{"numFound":1,"start":0,"maxScore":0.7698604,"docs":[
> {
> "id":"F8V7067-APL-KIT",
> "name":"Belkin Mobile Power Cord for iPod w/ Dock",
> "score":0.7698604,
> "[elevated]":false}]
> }},
> {
> "groupValue":"inc",
> "doclist":{"numFound":1,"start":0,"maxScore":0.28869766,"docs":[
> {
> "id":"MA147LL/A",
> "name":"Apple 60 GB iPod with Video Playback Black",
> "score":0.28869766,
> "[elevated]":true}]
> }}]}}}
> the elevate.xml defines the following rules :
> <query text="ipod">
> <doc id="MA147LL/A" /> <!-- put the actual ipod at the top -->
> <doc id="IW-02" exclude="true" /> <!-- exclude this cable -->
> </query>
>
> </elevate>
