Issue with 2WD and 4WD in query

[Brendan Grainger]

Hi,

I hope you can help me. I'm having an odd problem with solr. I have a  
field that could be represent a car. A car could have a name like  
"Silverado" or could be something like "Silverado 2WD" to denote the  
2 wheel drive version of the car. Anyway, all is well when I search  
over the field for "Silverado", but when I try searching for  
"2WD" (doesn't matter what case) nothing is returned. Same applies  
for "Silverado 2WD" etc. I currently have the field defined as text, ie:

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

But I've also tried defining my own (simpler) field with no luck. FYI  
my text field is defined like this:

    <fieldType name="text" class="solr.TextField"  
positionIncrementGap="100">
      <analyzer type="index">
        <!-- This is supposed to remove HTML tags before indexing -->
        <tokenizer class="solr.HTMLStripWhitespaceTokenizerFactory"/>
        <!--
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
         -->
        <filter class="solr.StopFilterFactory" ignoreCase="true"  
words="stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory"  
generateWordParts="1" generateNumberParts="1" catenateWords="1"  
catenateNumbers="1" catenateAll="0"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPorterFilterFactory"  
protected="protwords.txt"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory"  
synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true"  
words="stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory"  
generateWordParts="1" generateNumberParts="1" catenateWords="0"  
catenateNumbers="0" catenateAll="0"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPorterFilterFactory"  
protected="protwords.txt"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
    </fieldType>

Any help?

Thanks!
Brendan
