Thanks for your answer, I am trying now with this custom text field:
<fieldType name="textIntact" class="solr.TextField"
positionIncrementGap="100" >
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="0"
catenateWords="0" catenateNumbers="0" catenateAll="0"
expand="0" splitOnCaseChange="0"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
And still it does not find "blah" when using the wildcard and searching for
"blah*". Am I missing something?
Thanks,
Bruno
