Here is the test steps:
1. enable QueryElevationComponent in solr server, please refer to wiki https://cwiki.apache.org/confluence/display/solr/The+Query+Elevation+Component
2. call the solr with following parameters (I am using id as uniqueKey in my schema):
make sure the document of <document_id> existed in your index.
check the response to see if [elevated] value is true for document with id <document_id>
We also need to verify another case with elevate.xml defined, instead of passing elevateIds in API.
Let me know if you need more information.
