Applying synonyms increase the data size from MB to GBs

[rajini maski]

Applying synonyms increased the data size from 28 mb to 10.3 gb

   Before enabling synonyms to the a field , the data size was 28mb.  Now ,
after applying synonyms I see that data folder size has increased to 10.3
gb.

Attached is schema field type for that field:


 <fieldType name="textBODY" class="solr.TextField"
positionIncrementGap="100" >
      <analyzer>
        <filter class="solr.SynonymFilterFactory"
synonyms="BODYTaxonomy.txt" ignoreCase="true" expand="true"/>
       <filter class="solr.SynonymFilterFactory" synonyms="ObsTaxo.txt"
ignoreCase="true" expand="true"/>
       <filter class="solr.SynonymFilterFactory" synonyms="MTaxonomy.txt"
ignoreCase="true" expand="true"/>
        <filter class="solr.SynonymFilterFactory" synonyms="MicTaxo.txt"
ignoreCase="true" expand="true"/>
       <filter class="solr.SynonymFilterFactory" synonyms="SpTaxonomy.txt"
ignoreCase="true" expand="true"/>
       <filter class="solr.SynonymFilterFactory"
synonyms="ParameterTaxonomy.txt" ignoreCase="true" expand="true"/>
       <filter class="solr.SynonymFilterFactory" synonyms="STaxo.txt"
ignoreCase="true" expand="true"/>
  <filter class="solr.LowerCaseFilterFactory"/>
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
  <filter class="solr.SnowballPorterFilterFactory" language="English"
protected="protwords.txt"/>
      </analyzer>
    </fieldType>

All the attached synonym files are not more than 200KB


What might be the reason for this? Any config changes to be done?
