----------------------------------------------------------------

SOLR-11021 made specifying elevate.xml optional but seems not handled the case 
while applying elevation at query time . Based on Git history, SOLR-11865 did 
refactoring which introduces initialized variable. When config-file is not 
specified, exception is thrown but this 
[method|https://github.com/apache/lucene-solr/blob/3ae0ca23d937bef2865689748ac9e556b40aff38/solr/core/src/java/org/apache/solr/handler/component/QueryElevationComponent.java#L284]
 ensures exception is not propagated to caller (expected behavior SOLR-11021) 
but initialized variable is still false. 

The prepare method checks for 
[initialization|https://github.com/apache/lucene-solr/blob/3ae0ca23d937bef2865689748ac9e556b40aff38/solr/core/src/java/org/apache/solr/handler/component/QueryElevationComponent.java#L458]
 

I think fix should be simple - to return immediately when config-file instead 
of throwing the error(there might 1 or more places where this need to be 
handled). Let me know if you are interested in providing the patch, would be 
happy to review and commit it

> When i remove elevate.xml line from solrconfig.xml plus the file, elevation 
> is not working and no error is logged.
> We put the ids directly in the query and we are not using the default fields 
> or ids, so the xml is completely useless, but required to let the elevation 
> component work, example query:
> {code:java}http://staging.qeep.net:8983/solr/profile_v2/elevate?q=%2Bapp_sns%3A%20qeep&sort=random_4239%20desc,%20id%20desc&elevateIds=361018,361343&forceElevation=true{code}
