Description

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>
