Question

I am getting the following error when trying to do a search…

 org.apache.lucene.util.automaton.TooComplexToDeterminizeException: Determinizing automaton with 1007861 states and 2653488 transitions would require more than 10000 effort. at

The schema definition for the search field is as follows:

<field name="street_name_code" type="text_exact_fuzzy" indexed="true" stored="true"/>

<fieldType name="text_exact_fuzzy" class="solr.TextField" omitNorms="false">
 <analyzer type="index">
   <filter class="solr.PatternReplaceFilterFactory" pattern="([|]+)" replacement=" " replace="all"/>      
   <tokenizer class="solr.StandardTokenizerFactory"/>
   <filter class="solr.LowerCaseFilterFactory"/>
   <filter class="solr.FlattenGraphFilterFactory"/>        
 </analyzer>
 <analyzer type="query">
   <filter class="solr.PatternReplaceFilterFactory" pattern="([,]+)" replacement=" " replace="all"/>      
   <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />

   <filter class="solr.SynonymGraphFilterFactory" synonyms="mysynonyms.txt"/>
   <filter class="solr.FlattenGraphFilterFactory"/>        
 </analyzer>
</fieldType>

The definition of the suggest component is as follows:

  <searchComponent name="suggest" class="solr.SuggestComponent">
    <lst name="suggester">
      <str name="name">mySuggester</str>
      <str name="lookupImpl">FuzzyLookupFactory</str>
      <str name="exactMatchFirst">true</str>
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>
      <str name="field">street_name</str>
      <str name="suggestAnalyzerFieldType">text_exact_fuzzy</str>
      <str name="buildOnCommit">true</str>
      <str name="maxEdits">1</str>
      <str name="storeDir">fuzzy_suggestions</str>
    </lst>    
  </searchComponent>

The query that throws the error is:

http://localhost:8986/solr/street_names/suggest?suggest.dictionary=mySuggester&wt=xml&suggest.q=NELSON+BAY+DRIVE+DRIVE+ERN+BAY

Whereas the one that works is (the difference is only one DRIVE in the below query):

http://localhost:8986/solr/street_names/suggest?suggest.dictionary=mySuggester&wt=xml&suggest.q=NELSON+BAY+DRIVE+ERN+BAY

Can anyone please tell me how to arrange the synonyms file so that this error can be eliminated?
