如何在solr中配置IndexBasedSpellChecker？

Question

我使用Solr的5.2，我想用IndexBasedSpellChecker我searchHandler裏面，這是我IndexBasedSpellChecker的SearchComponent：

<searchComponent class="solr.SpellCheckComponent" name="spellcheck"> 
 
<str name="queryAnalyzerFieldType">text_en_general</str> 
 
    <lst name="spellchecker"> 
 
    <str name="name">default</str> 
 
<!--specify a field to use for the suggestions--> 
 
    <str name="field">body-en</str> 
 
    <str name="classname">solr.IndexBasedSpellChecker</str> 
 
    
 
    <!-- <str name="distanceMeasure">internal</str> --> 
 
<!--The accuracy setting defines the threshold for a valid suggestion--> 
 
<!-- <float name="accuracy">0.05</float> --> 
 
<!-- maxEdits defines the number of changes to the term to allow--> 
 
    <int name="maxEdits">2</int> 
 
<!--defines the minimum number of characters the terms should share--> 
 
    <int name="minPrefix">1</int> 
 
<!--defines the maximum number of possible matches to review before returning results--> 
 
    <int name="maxInspections">5</int> 
 
<!--defines how many characters must be in the query before suggestions are provided--> 
 
    <int name="minQueryLength">4</int> 
 
<!-- sets the maximum threshold for the number of documents a term must appear in before being considered as a suggestion--> 
 
    <float name="maxQueryFrequency">0.01</float> 
 
<!--sets the minimum number of documents a term must appear in--> 
 
    <float name="thresholdTokenFrequency">.01</float>

這裏我的問題是，當我想使用準確性，它給了我這個錯誤

Caused by: org.apache.solr.common.SolrException: java.lang.Float cannot be cast to java.lang.String 

當我評論這個設置，它會給我一個其他錯誤使用distanceMeasure：

org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error loading class 'internal' 

，當我COMENT他們兩個，我無法從我的拼寫檢查得到的結果，當我查詢一個短語，它只是拼寫檢查的短語的第一個字，是什麼我應該做？

Answer 1

我看不到完整的組件描述，所以我無法確定發生了什麼事情。如果該組件內有多個拼寫檢查程序，請確保它具有相同的字段名稱。

<str name="field">body-en</str> 

下面的代碼對我的作品：

<searchComponent name="spellcheck" class="solr.SpellCheckComponent"> 
    <lst name="spellchecker"> 
     <str name="name">default</str> 
     <str name="field">variations</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">0.01</float> 
     <float name="thresholdTokenFrequency">.01</float> 
    </lst> 
</searchComponent> 

與下面的請求處理程序的代碼片段：

<str name="spellcheck.dictionary">default</str> 
<str name="spellcheck">true</str> 
<str name="spellcheck.count">3</str> 
<str name="spellcheck.onlyMorePopular">true</str> 
<str name="spellcheck.extendedResults">true</str> 
<str name="spellcheck.collate">true</str> 

希望它能幫助！
