Hello everyone :)
I have a product called "xbox" indexed, and when the user search for
either "x-box" or "x box" i want the "xbox" product to be
returned. I'm new to Solr, and from reading online, I thought I need
to use WordDelimiterFilterFactory for "x-box" case, and
WordBreakSolrSpellChecker for "x box" case. Is this correct?
(1) In my schema file, this is what I changed:
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1"
generateNumberParts="1" catenateWords="1" catenateNumbers="1"
catenateAll="1" splitOnCaseChange="0" preserveOriginal="1"/>
But I don't see the xbox product returned when the search term is
"x-box", so I must have missed something....
(2) I tried to use WordBreakSolrSpellChecker together with
DirectSolrSpellChecker as shown below, but the WordBreakSolrSpellChecker
never got used:
<searchComponent name="wc_spellcheck"
class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">wc_textSpell</str>
<lst name="spellchecker">
<str name="name">default</str>
<str name="field">spellCheck</str>
<str name="classname">solr.DirectSolrSpellChecker</str>
<str name="distanceMeasure">internal</str>
<float name="accuracy">0.3</float>
<int name="maxEdits">2</int>
<int name="minPrefix">1</int>
<int name="maxInspections">5</int>
<int name="minQueryLength">3</int>
<float name="maxQueryFrequency">0.01</float>
<float name="thresholdTokenFrequency">0.004</float>
</lst>
<lst name="spellchecker">
<str name="name">wordbreak</str>
<str name="classname">solr.WordBreakSolrSpellChecker</str>
<str name="field">spellCheck</str>
<str name="combineWords">true</str>
<str name="breakWords">true</str>
<int name="maxChanges">10</int>
</lst>
</searchComponent>
<requestHandler name="/spellcheck"
class="org.apache.solr.handler.component.SearchHandler">
<lst name="defaults">
<str name="df">SpellCheck</str>
<str name="spellcheck">true</str>
<str name="spellcheck.dictionary">default</str>
<str name="spellcheck.dictionary">wordbreak</str>
<str name="spellcheck.build"> true</str>
<str name="spellcheck.onlyMorePopular">false</str>
<str name="spellcheck.count">10</str>
<str name="spellcheck.collate">true</str>
<str name="spellcheck.collateExtendedResults">false</str>
</lst>
<arr name="components">
<str>wc_spellcheck</str>
</arr>
</requestHandler>
I tried to build the dictionary this way:
http://localhost/solr/coreName/select?spellcheck=true&spellcheck.build=true,
but the response returned is this:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">0</int>
<lst name="params">
<str name="spellcheck.build">true</str>
<str name="spellcheck">true</str>
</lst>
</lst>
<str name="command">build</str>
<result name="response" numFound="0" start="0"/>
</response>
What's the correct way to build the dictionary?
Even though my requestHandler's name="/spellcheck", i wasn't able to
use
http://localhost/solr/coreName/spellcheck?spellcheck=true&spellcheck.build=true
.. is there something wrong with my definition above?
(3) I also tried to use WordBreakSolrSpellChecker without the
DirectSolrSpellChecker as shown below:
<searchComponent name="wc_spellcheck"
class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">wc_textSpell</str>
<lst name="spellchecker">
<str name="name">default</str>
<str name="classname">solr.WordBreakSolrSpellChecker</str>
<str name="field">spellCheck</str>
<str name="combineWords">true</str>
<str name="breakWords">true</str>
<int name="maxChanges">10</int>
</lst>
</searchComponent>
<requestHandler name="/spellcheck"
class="org.apache.solr.handler.component.SearchHandler">
<lst name="defaults">
<str name="df">SpellCheck</str>
<str name="spellcheck">true</str>
<str name="spellcheck.dictionary">default</str>
<!--<str name="spellcheck.dictionary">wordbreak</str> -->
<str name="spellcheck.build"> true</str>
<str name="spellcheck.onlyMorePopular">false</str>
<str name="spellcheck.count">10</str>
<str name="spellcheck.collate">true</str>
<str name="spellcheck.collateExtendedResults">false</str>
</lst>
<arr name="components">
<str>wc_spellcheck</str>
</arr>
</requestHandler>
And still unable to see WordBreakSolrSpellChecker being called anywhere.
Would someone kindly help me?
Many thanks,
Jia
