Unable to match partial word

[Van Tassell, Kristian]

I'm doing a search for "prod" and would assume it would pull back matches for 
product, production, etc. but I get zero hits. Any ideas?

Here is my field type:

<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
                <tokenizer class="solr.WhitespaceTokenizerFactory"/>
               <filter class="solr.StopFilterFactory" ignoreCase="true" 
words="stopwords.txt" enablePositionIncrements="true"
                              />
               <filter class="solr.WordDelimiterFilterFactory" 
generateWordParts="1" generateNumberParts="1" catenateWords="1" 
catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
               <filter class="solr.LowerCaseFilterFactory"/>
               <filter class="solr.SnowballPorterFilterFactory"

        </analyzer>
        <analyzer type="query">

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

               <filter class="solr.WordDelimiterFilterFactory"
