Solr - example spell checker not working - search

Question

I have set up the spellchecker for the example installation configuration that comes with Solr. I have followed their instructions for the spellchecker here: [http://wiki.apache.org/solr/SpellCheckComponent][1]
The problem I have is that after following it exactly I still cannot get it to work?
The response when I build (http://localhost:8983/solr/spell?q=:&spellcheck.build=true&spellcheck.q=delll%20ultrashar&spellcheck=true)
looks as follows:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">14</int>
</lst>
<str name="command">build</str>
<result name="response" numFound="17" start="0">
...
</result>
<lst name="spellcheck">
<lst name="suggestions"/>
</lst>
</response>
And when I query with http://localhost:8983/solr/spell?q=:&spellcheck.q=delll+ultrashar&spellcheck=true&spellcheck.extendedResults=true
I get the following response
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<result name="response" numFound="17" start="0">
...
</result>
<lst name="spellcheck">
<lst name="suggestions">
<bool name="correctlySpelled">false</bool>
</lst>
</lst>
</response>
What gives? Am i missing something in my schema.xml?
The schema.xml is here: http://www.developermill.com/schema.xml
The solrConfig.xml is here: http://www.developermill.com/solrconfig.xml
The only change to the example files was the addition of the following in the solrconfig.xml:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<lst name="spellchecker">
<!--
Optional, it is required when more than one spellchecker is configured.
Select non-default name with spellcheck.dictionary in request handler.
-->
<str name="name">default</str>
<!-- The classname is optional, defaults to IndexBasedSpellChecker -->
<str name="classname">solr.IndexBasedSpellChecker</str>
<!--
Load tokens from the following field for spell checking,
analyzer for the field's type as defined in schema.xml are used
-->
<str name="field">spell</str>
<!-- Optional, by default use in-memory index (RAMDirectory) -->
<str name="spellcheckIndexDir">./spellchecker</str>
<!-- Set the accuracy (float) to be used for the suggestions. Default is 0.5 -->
<str name="accuracy">0.7</str>
<!-- Require terms to occur in 1/100th of 1% of documents in order to be included in the dictionary -->
<float name="thresholdTokenFrequency">.0001</float>
</lst>
<!-- Example of using different distance measure -->
<lst name="spellchecker">
<str name="name">jarowinkler</str>
<str name="field">lowerfilt</str>
<!-- Use a different Distance Measure -->
<str name="distanceMeasure">org.apache.lucene.search.spell.JaroWinklerDistance</str>
<str name="spellcheckIndexDir">./spellchecker</str>
</lst>
<!-- This field type's analyzer is used by the QueryConverter to tokenize the value for "q" parameter -->
<str name="queryAnalyzerFieldType">textSpell</str>
</searchComponent>
<!--

Answer 1

The textSpell field definition is in the wrong place. The following fragment should be within the types tag inside the schema.xml:
<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100" omitNorms="true">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StandardFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StandardFilterFactory"/>
</analyzer>
</fieldType>
After you've fixed that, everything should work I guess, but I'd suggest you to work on cleaning up a little bit your example, since it basically contains everything you can configure. You should keep just what you really need.
