Solr elevation: elevation configuration not changing my results

I'm trying to add elevation to Solr for a few different queries. I followed the instructions here: http://ift.tt/1tUC4gW

but the changes I made have had no effect. Here's what I've done.

• 
  

  Core 0 is online; Core 1 is offline. I've made all of my changes to Core 0 and reloaded Core 0 in the Solr Admin

  
  


• 
  

  In solr/core0/conf/solrconfig.xml, I added this XML:

  
  

-

<searchComponent name="elevator" class="org.apache.solr.handler.component.QueryElevationComponent" >
    <str name="queryFieldType">string</str>
    <str name="config-file">elevate.xml</str>
    <str name="forceElevation">true</str>
</searchComponent>

<requestHandler name="/elevate" class="solr.SearchHandler">
    <lst name="defaults">
        <str name="echoParams">explicit</str>
    </lst>
    <arr name="last-components">
        <str>elevator</str>
    </arr>
</requestHandler>

• In the same folder (solr/core0/conf) I created a file elevate.xml:

-

<elevate>

 <query text="ent">
  <doc id="ektron_4294973723" />
  <doc id="ektron_4294973721" />
  <doc id="ektron_4294973743" />
  <doc id="ektron_4294973791" />
  <doc id="ektron_4294973977" />
 </query>

 <query text="ear">
  <doc id="ektron_4294971473" />
 </query>

 <query text="nose">
  <doc id="ektron_4294971473" />
 </query>

 <query text="throat">
  <doc id="ektron_4294971473" />
 </query>

</elevate>

As far as I can tell, I've put everything in the correct locations. I reloaded the config file in Solr Admin, and when I view the config file in Solr Admin I can see the changes I've made. I don't see anything wrong with my syntax. Why isn't my elevation working?
