    [ https://issues.apache.org/jira/browse/SOLR-3936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13489039#comment-13489039 ] 

Michael Berger commented on SOLR-3936:
--------------------------------------

I tried to fix by myself:

"debug":{
    "queryBoosting":{
      "q":"ipod",
      "match":["MA147LL/A"]},
    "rawquerystring":"ipod",
    "querystring":"ipod",
    "parsedquery":"(text:ipod ((id:MA147LL/A)^10.0) -id:IW-02)/no_coord",
    "parsedquery_toString":"text:ipod ((id:MA147LL/A)^0.0) -id:IW-02",

I found that the boost factor is too low. 

I set a higher boost factor for booster.include in QueryElevationComponent.java and I get the expected result from my query.

> 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:
