Solr 4.0 How can I change the spellchecker analyse

问题:

I've just upgraded from 3.6.1 to 4.0 solr and the spelchecker stopped working. I'm using the standard config /spell request handler to test the spellchecking.

I keep getting the "All checkers need to use the same Analyzer" error. (https://svn.apache.org/repos/asf/lucene/dev/trunk/solr/core/src/java/org/apache/solr/spelling/ConjunctionSolrSpellChecker.java)

How can I change the spellchecker analysers so they are all the same?

This is the handler I'm using:

  <requestHandler name="/spell" class="solr.SearchHandler" startup="lazy">
    <lst name="defaults">
      <str name="df">text</str>
      <!-- Solr will use suggestions from both the 'default' spellchecker
           and from the 'wordbreak' spellchecker and combine them.
           collations (re-written queries) can include a combination of
           corrections from both spellcheckers -->
      <str name="spellcheck.dictionary">default</str>
      <str name="spellcheck.dictionary">wordbreak</str>
      <str name="spellcheck">on</str>
      <str name="spellcheck.extendedResults">true</str>       
      <str name="spellcheck.count">10</str>
      <str name="spellcheck.alternativeTermCount">5</str>
      <str name="spellcheck.maxResultsForSuggest">5</str>       
      <str name="spellcheck.collate">true</str>
      <str name="spellcheck.collateExtendedResults">true</str>  
      <str name="spellcheck.maxCollationTries">10</str>
      <str name="spellcheck.maxCollations">5</str>         
    </lst>
    <arr name="last-components">
      <str>spellcheck</str>
    </arr>
</requestHandler>

I know that this is not the way to use it in production.

The answer lies in the configuration of the spell check "searchComponent" in solrconfig.xml. There, each spellchecker entry should have the same value for the "field" and/or "fieldType" attributes.
