Subject Re: questions on Solr WordBreakSolrSpellChecker and WordDelimiterFilterFactory
Date Fri, 18 Jul 2014 09:31:16 GMT
hello,

for WordDelimiterFilterFactory:

this is an exemple in schema.xml to folow:

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

<fieldType name="textSpell" class="solr.TextField"
positionIncrementGap="100" omitNorms="true">
        <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.PatternReplaceFilterFactory"
pattern="^(\p{Punct}*)(.*?)(\p{Punct}*)$" replacement="$2"/>
        <filter class="solr.LengthFilterFactory" min="3" max="20" />
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
        <filter class="solr.StopFilterFactory" words="stopwords.txt"
ignoreCase="true"/>
        <filter class="solr.WordDelimiterFilterFactory"/>   
		
        </analyzer>
		
        <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.PatternReplaceFilterFactory"
pattern="^(\p{Punct}*)(.*?)(\p{Punct}*)$" replacement="$2"/>
        <filter class="solr.LengthFilterFactory" min="3" max="20" />
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
        <filter class="solr.StopFilterFactory" words="stopwords.txt"
ignoreCase="true"/>
        <filter class="solr.WordDelimiterFilterFactory"/>
        </analyzer>
    </fieldType>

and for WordBreakSolrSpellChecker  folow this in solrconfig.xml:

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">

    <str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">
      <str name="name">wordbreak</str>
      <str name="classname">solr.WordBreakSolrSpellChecker</str>      
      <str name="field">spell</str>
      <str name="combineWords">true</str>
      <str name="breakWords">true</str>
      <int name="maxChanges">10</int>
    </lst>
</searchComponent>

<requestHandler name="/spellcheck" class="solr.SearchHandler">
<lst name="defaults">
       <str name="echoParams">explicit</str>
       <int name="rows">10</int>
<str name="qf">your field</str>
str name="qt">spellchecker</str>
	   <str name="cmd">rebuild</str>
<str name="spellcheck.dictionary">wordbreak</str>
<str name="spellcheck">on</str>
      <str name="spellcheck.extendedResults">true</str>       
      <str name="spellcheck.count">10</str>
      <str name="spellcheck.alternativeTermCount">5</str>
      <str name="spellcheck.maxResultsForSuggest">5</str>   
	  
      <str name="spellcheck.collate">true</str>
	  <str name="spellcheck.onlyMorePopular">true</str>
	  <str name="spellcheck.maxCollations">5</str> 
      <str name="spellcheck.collateExtendedResults">true</str>
<str name="spellcheck">true</str>
	  <str name="spellcheck.build">true</str>	 
<arr name="last-components">
	  <str>spellcheck</str> 
    </arr>	
 </requestHandler>
