KeywordTokenizerFactory with SynonymFilterFactory

[Peyman Faratin]

Hi

I have the following 2 field types

<fieldType name="tokenizer1" class="solr.TextField" sortMissingLast="true" 
autoGeneratePhraseQueries="true">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" 
ignoreCase="false" expand="true"/> 
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
</fieldType>


<fieldType name="tokenizer2" class="solr.TextField" sortMissingLast="true" 
autoGeneratePhraseQueries="true">
      <analyzer type="index">
        <tokenizer class="solr.KeywordTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.KeywordTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" 
ignoreCase="false" expand="true"/> 
      </analyzer>
</fieldType>    

The problem I am seeing is if I have an entry as this in the "synonyms.txt" file

helping hand => assistance

then issuing "helping hand" query (with dismax) to the field tokenized with 
tokenizer1 returns the correct query ("assistance") whereas there is no synonym 
mapping for tokenizer2 (confirmed in Solr admin panel). 

Am I doing something wrong?

thank you
