Hi,

Is it possible to create a database index on one of the columns in a schema 
being defined via indexer.xml and _auxiliary.xml when creating an ImageMosaic 
store?
Let's use an example from the docs....say we wanted to create a database index 
on "updated" is there a way to define that in the config below?

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Indexer>
  <domains>
    <domain name="time">
       <attributes><attribute>time</attribute></attributes>
    </domain>
    <domain name="elevation">
       <attributes><attribute>elevation</attribute></attributes>
    </domain>
    <domain name="fileDate">
       <attributes><attribute 
ref="fileDateCollector">fileDate</attribute></attributes>
    </domain>
    <domain name="updated">
       <attributes><attribute 
ref="updatedCollector">updated</attribute></attributes>
    </domain>
  </domains>
  <schemas>
    <schema name="default">
      
<attributes>the_geom:Polygon,location:String,imageindex:Integer,time:java.util.Date,elevation:Double,fileDate:java.util.Date,updated:java.util.Date</attributes>
    </schema>
  </schemas>
  <coverages>
    <coverage>
      <name>V</name>
      <schema ref="default"></schema>
      <domains>
        <domain ref="time" />
        <domain ref="elevation" />
        <domain ref="fileDate" />
        <domain ref="updated" />
      </domains>
    </coverage>
    <coverage>
      <name>O3</name>
      <schema ref="default" />
      <domains>
        <domain ref="time" />
        <domain ref="elevation" />
        <domain ref="fileDate" />
        <domain ref="updated" />
      </domains>
    </coverage>
    <coverage>
      <name>NO2</name>
      <schema ref="default" />
      <domains>
        <domain ref="time" />
        <domain ref="elevation" />
        <domain ref="fileDate" />
        <domain ref="updated" />
      </domains>
    </coverage>
  </coverages>
  <collectors>
  <collector name="fileDateCollector">
    <value>[0-9]{8}</value>
    <spi>TimestampFileNameExtractorSPI</spi>
    <mapped>fileDate</mapped>
  </collector>
  <collector name="updatedCollector">
    <value>MODIFY_TIME</value>
    <spi>RuntimeExtractorSPI</spi>
    <mapped>updated</mapped>
  </collector>
  </collectors>
  <parameters>
      <parameter name="AuxiliaryFile" value="polyphemus-test.xml" />
      <parameter name="AbsolutePath" value="true" />
  </parameters>
</Indexer>


thanks,

Marc
