--------------------------------------
Hello. I am hitting
http://localhost:8983/solr/select/?q=pizza&spellcheck=true&spellcheck.dictionary=default&spellcheck.build=true
when trying to build the dictionary. My config looks this this:
<searchComponent name="spellcheck"
class="org.apache.solr.handler.component.SpellCheckComponent">
<lst name="defaults">
<!-- omp = Only More Popular -->
<str name="spellcheck.onlyMorePopular">false</str>
<!-- exr = Extended Results -->
<str name="spellcheck.extendedResults">false</str>
<!-- The number of suggestions to return -->
<str name="spellcheck.count">1</str>
</lst>
<lst name="spellchecker">
<str
name="classname">org.apache.solr.spelling.IndexBasedSpellChecker</str>
<str name="name">default</str>
<str name="fieldType">text_ws</str>
<str
name="indexDir">/usr/local/apache/lucene/solr1home/solr/data/spellchecker</str>
</lst>
<lst name="spellchecker">
<str name="classname">org.apache.solr.spelling.FileBasedSpellChecker</str>
<str name="name">external</str>
<str name="sourceLocation">spellings.txt</str>
<str name="fieldType">text_ws</str>
<str name="characterEncoding">UTF-8</str>
<str
name="indexDir">/usr/local/apache/lucene/solr1home/solr/data/spellchecker</str>
</lst>
</searchComponent>
And the NPE is:

> Expose the Lucene contrib SpellChecker as a Search Component. Provide the
> following features:
> * Allow creating a spell index on a given field and make it possible to have
> multiple spell indices -- one for each field
> * Give suggestions on a per-field basis
> * Given a multi-word query, give only one consistent suggestion
> * Process the query with the same analyzer specified for the source field and
> process each token separately
> * Allow the user to specify minimum length for a token (optional)
> Consistency criteria for a multi-word query can consist of the following:
> * Preserve the correct words in the original query as it is
> * Never give duplicate words in a suggestion
