Facet for multiple values field

[Giri]

Hi,

I am trying to get the facet values from a field that contains multiple
words, for example:

 I have a field "keywords"

 and values for this: Keywords=  relative humidity, air temperature,
atmospheric moisture

 Please note: I am combining multiple keywords in to one single field, with
comma delimiter

 When I query for facet, I am getting some thing like:

 - relative (10)

 - humidity (10)

 - temperature (5)


But I really need to display:

 - relative humidity(10)

 - air temperature(5)


How can I do this? I know I am missing something in my schema field type
declaration. I would appreciate if any one can post me an example schema
field type that can handle this.

Thanks!


Here is my schema excerpt:

   <fieldtype name="text" class="solr.TextField" positionIncrementGap="100">

      <analyzer type="index">

          <tokenizer class="solr.WhitespaceTokenizerFactory"/>

          <!-- in this example, we will only use synonyms at query time

          <filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>

          -->

          <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1"/>

          <filter class="solr.StopFilterFactory" ignoreCase="true"/>

          <filter class="solr.LowerCaseFilterFactory"/>

      </analyzer>

      <analyzer type="query">

          <tokenizer class="solr.WhitespaceTokenizerFactory"/>

          <filter class="solr.StopFilterFactory" ignoreCase="true"/>

          <filter class="solr.LowerCaseFilterFactory"/>

      </analyzer>

    </fieldtype>



And, the I declared the field as:

<field name="sensor" type="text" indexed="true" stored="true"/>
