unexpected wildcard results

[Matthew Roth]

Hi List,

We are noting unexpected wildcard results. For example, the following query

 text:"witch*"

will match witch, witches, but not witchcraft. We would
anticipate witchcraft would also be matched. I suspect the issue may lie
with the field definition.

 <fieldType name="text_en" class="solr.TextField"
positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
          <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="lang/stopwords_en.txt"
                />
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPossessiveFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory"
protected="protwords.txt"/>
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="lang/stopwords_en.txt"
                />
        <filter class="solr.LowerCaseFilterFactory"/>
  <filter class="solr.EnglishPossessiveFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory"
protected="protwords.txt"/>
         <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
    </fieldType>


May anyone offer any insight.

Best,
Matt
