Solr suggest - How to define solr suggest as case insensitive

[Mysurf Mail <st...@gmail.com>]

My suggest (spellchecker) is returning case sensitive answers. (I use it to
autocomplete - dog and Dog return different phrases)\

my suggest is defined as follows - in solrconfig -

 <searchComponent class="solr.SpellCheckComponent" name="suggest">
<lst name="spellchecker">
    <str name="name">suggest</str>
    <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
    <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
    <str name="field">suggest</str>  <!-- the indexed field to derive
suggestions from -->
    <float name="threshold">0.005</float>
    <str name="buildOnCommit">true</str>
    <!--<str name="sourceLocation">american-english</str>-->
</lst>
</searchComponent>
<requestHandler
class="org.apache.solr.handler.component.SearchHandler"
name="/suggest">
    <lst name="defaults">
        <str name="spellcheck">true</str>
        <str name="spellcheck.dictionary">suggest</str>
        <str name="spellcheck.onlyMorePopular">true</str>
        <str name="spellcheck.count">5</str>
        <str name="spellcheck.collate">true</str>
    </lst>
    <arr name="components">
        <str>suggest</str>
    </arr>
</requestHandler>

in schema

<field name="suggest" type="phrase_suggest" indexed="true"
stored="true" required="false" multiValued="true"/>

and

<copyField source="Name" dest="suggest"/>

and

<fieldtype name="phrase_suggest" class="solr.TextField">
  <analyzer>
    <tokenizer class="solr.KeywordTokenizerFactory"/>
    <filter class="solr.PatternReplaceFilterFactory"
            pattern="([^\p{L}\p{M}\p{N}\p{Cs}]*[\p{L}\p{M}\p{N}\p{Cs}\_]+:)|([^\p{L}\p{M}\p{N}\p{Cs}])+"
            replacement=" " replace="all"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.TrimFilterFactory"/>
  </analyzer>
</fieldtype>

: This is probably because your dictionary is made up of all lower case tokens,

: case would be when you query the spellchecker you send lower case queries

You can init the SpellCheckComponent with a "queryAnalyzerFieldType" 
option that will control what analysis happens.  ie...

  <!-- This field type's analyzer is used by the QueryConverter to tokenize the value for "q" parameter -->
  <str name="queryAnalyzerFieldType">phrase_suggest</str>


...it would be nice if this defaulted to using the fieldType of hte field 
you configure on the Suggester, but not all Impls are based on the index 
(you might be using an external dict file) so it has to be explicitly 
configured, and defaults to using a simple WhitespaceAnalyzer.

This is probably because your dictionary is made up of all lower case tokens,
but when you query the spell-checker similar analysis doesnt happen. Ideal
case would be when you query the spellchecker you send lower case queries
