fuzzy search issue with PatternTokenizer Factory

[meghana]

I m using Solr4.2 , I have changed my text field definition, to use the
Solr.PatternTokenizerFactory instead of Solr.StandardTokenizerFactory , and
changed my schema defination as below

<fieldType name="text_token" class="solr.TextField"
positionIncrementGap="100">
      <analyzer type="index">
       <tokenizer class="solr.PatternTokenizerFactory"
pattern="[^a-zA-Z0-9&amp;\-']|\d{0,4}s:" />
       <filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="false" />
       
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
      <analyzer type="query">
       <tokenizer class="solr.PatternTokenizerFactory"
pattern="[^a-zA-Z0-9&amp;\-']|\d{0,4}s:" />
       <filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords_extra_query.txt" enablePositionIncrements="false" />
       <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
      <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
    </fieldType>

after doing so, fuzzy search do not seems to working properly as it was
working before. 

I m searching with search term : worde~1 

on search , before it was returning , around 300 records , but now its
returning only 5 records. not sure what can be issue.

Can anybody help me to make it work!!
