问题
I am get stuck in middle of Solr. I need only most popular words w.r.t query. I have used phonetic filter on both index and query but here the problem is that it is giving too many terms. I need only few terms which are very specific to the query.
schema.xml
<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<filter class="solr.TrimFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.PhoneticFilterFactory" encoder="DoubleMetaphone" inject="true"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
<analyzer type="query">
<filter class="solr.TrimFilterFactory"/>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.PhoneticFilterFactory" encoder="DoubleMetaphone" inject="true"/>
</analyzer>
</fieldType>
solrconfig.xml
<lst name="spellchecker">
<str name="name">default</str>
<str name="field">term</str>
<str name="classname">solr.DirectSolrSpellChecker</str>
<str name="distanceMeasure">internal</str>
<float name="accuracy">0.5</float>
<int name="maxEdits">2</int>
<int name="minPrefix">1</int>
<int name="maxInspections">5</int>
<int name="minQueryLength">4</int>
<float name="maxQueryFrequency">0.90</float>
<float name="thresholdTokenFrequency">0.90</float>
</lst>
<requestHandler name="/spell" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="df">term</str>
<str name="spellcheck.dictionary">default</str>
<str name="spellcheck">on</str>
<str name="spellcheck.extendedResults">true</str>
<str name="spellcheck.count">10</str>
<str name="spellcheck.alternativeTermCount">10</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>
<str name="spellcheck.onlyMorePopular">true</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
I am also using thresholdTokenFrequency but it not working I have tried by varying the value of threshold between 0 and 1. but it always gives same result. Any help ?
