Spell-Check Component Functionality

[rajini maski]

All,

    I am trying apply the Solr spell check component functionality to our
data.

The configuration set up I needed to make for it by updating config.xml and
schema.xml is done as follows..
Please let me know if any errors in it.

 I am not getting any suggestions in suggestion tags of solr output xml.

I indexed word "Crust" to the field textSpell that is enabled for spell
check and then I searched for
"Curst"

The queries i tried were :
http://localhost:8909/solr/spell?q=Curst&spellcheck=true&spellcheck.collate=true&spellcheck.build=true&spellcheck.q=true

http://localhost:8909/solr/spell?q=Cruste&spellcheck=true&spellcheck.collate=true&spellcheck.build=true&spellcheck.q=true&spellcheck.dictionary=default


The CONFIG.XML :

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
    <lst name="spellchecker">
      <str name="name">default</str>
      <str name="field">spell</str>
      <str name="spellcheckIndexDir">./spellchecker</str>
    </lst>

    <!-- a spellchecker that uses a different distance measure -->
    <lst name="spellchecker">
      <str name="name">jarowinkler</str>
      <str name="field">lowerfilt</str>
      <str
name="distanceMeasure">org.apache.lucene.search.spell.JaroWinklerDistance</str>
      <str name="spellcheckIndexDir">./spellchecker2</str>
    </lst>
     <str name="queryAnalyzerFieldType">textSpell</str>
</searchComponent>

<requestHandler name="/spell" class="solr.SearchHandler" lazy="true">
    <lst name="defaults">
<str name="spellcheck.dictionary">default</str>
      <!-- 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>
    <arr name="last-components">
      <str>spellcheck</str>
    </arr>
  </requestHandler>



SCHEMA:

<fieldType name="textSpell" class="solr.TextField"
positionIncrementGap="100">
  <analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
  <analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>


<field name="spell"  type="textSpell"  indexed="true" stored="true" />


If any error in above that is not enabling spell check please let me know.

The output I am getting is like null  suggetions

<lst>
<Suggesstions/>
</lst>
