Challenge in implementing suggester over huge chunks of text

[innovationchef]

I added the following XML to the solrconfig.xml file for implementing suggester module.

 <searchComponent name="suggest" class="solr.SuggestComponent">
      <lst name="suggester">
        <str name="name">mySuggester</str>
        <str name="lookupImpl">FuzzyLookupFactory</str>
        <str name="dictionaryImpl">DocumentDictionaryFactory</str>
        <str name="field">BioChemEntity.description</str>
        <str name="suggestAnalyzerFieldType">string</str>
      </lst>
    </searchComponent>
    <requestHandler name="/suggest" class="solr.SearchHandler"
                    startup="lazy" >
      <lst name="defaults">
        <str name="suggest">true</str>
        <str name="suggest.count">10</str>
      </lst>
      <arr name="components">
        <str>suggest</str>
      </arr>
    </requestHandler>

This would capture the BioChemEntity.description entries and populate the suggester dictionary that is used internally by Solr to provide suggestions.

The suggestions were captured by the following -
http://localhost:8983/solr/solr_core_name/suggest?suggest=true&suggest.build=true&suggest.dictionary=mySuggester&suggest.q=can
to get suggestions for the word starting with 'can'. However, it throws an error in building up the dictionary. When the above link is posted on the browser, I receive an error (attaching the error file). The error means that Solr was not able to build its suggester dictionary for 106713 docs(that I indexed in one go) while using the description of samples.

Note: Description in biochementities contains huge chunks of text.
