如何Solr的整理工作

Question

我按照從Solr中的文檔中的拼寫檢查的例子。

我已經使用了CONFIGS：

<!-- a spellchecker built from a field of the main index --> 
<lst name="spellchecker"> 
    <str name="name">default</str> 
    <str name="field">name_spell</str> 
    <str name="classname">solr.DirectSolrSpellChecker</str> 
    <!-- the spellcheck distance measure used, the default is the internal levenshtein --> 
    <str name="distanceMeasure">internal</str> 
    <!-- minimum accuracy needed to be considered a valid spellcheck suggestion --> 
    <float name="accuracy">0.5</float> 
    <!-- the maximum #edits we consider when enumerating terms: can be 1 or 2 --> 
    <int name="maxEdits">2</int> 
    <!-- the minimum shared prefix when enumerating terms --> 
    <int name="minPrefix">1</int> 
    <!-- maximum number of inspections per result. --> 
    <int name="maxInspections">5</int> 
    <!-- minimum length of a query term to be considered for correction --> 
    <int name="minQueryLength">4</int> 
    <!-- maximum threshold of documents a query term can appear to be considered for correction --> 
    <float name="maxQueryFrequency">0.01</float> 
    <!-- uncomment this to require suggestions to occur in 1% of the documents --> 
    <!-- <float name="thresholdTokenFrequency">.01</float> --> 

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

處理程序：

<requestHandler name="/spell" class="solr.SearchHandler" startup="lazy"> 
    <lst name="defaults"> 
     <str name="spellcheck.dictionary">default</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.collateExtendedResults">true</str> 
     <str name="spellcheck.maxCollationTries">10</str> 
     <str name="spellcheck.maxCollations">5</str>   
    </lst> 
    <arr name="last-components"> 
     <str>spellcheck_new</str> 
    </arr> 
    </requestHandler> 

架構字段：

<field name="attribute_key" type="text" indexed="true" stored="true" multiValued="false" /> 
    <field name="spell_check_field" type="text_spell" indexed="true" stored="false" multiValued="true"/> 
    <copyField source="attribute_key" dest="spell_check_field" /> 
    <field name="name_spell" type="text_general" indexed="true" stored="false" multiValued="false"/> 
    <copyField source="attribute_key" dest="name_spell" /> 
    <field name="attribute_key_tag" type="tag" stored="false" omitTermFreqAndPositions="true" omitNorms="true" multiValued="true"/> 
    <copyField source="attribute_key" dest="attribute_key_tag" multiValued="true"/> 
    <field name="attribute_value" type="string" indexed="false" stored="true" multiValued="false" /> 
    <defaultSearchField>attribute_key</defaultSearchField> 

我看到的建議完美的工作。但是整理數組對於所有查詢都是空的。

防爆查詢：

http://localhost:8984/solr/spell_check/spell?spellcheck.q=nike%20shoes&spellcheck=true&spellcheck.collate=true&wt=json&spellcheck=true&spellcheck.extendedResults=true&spellcheck.collate=true 

結果：

"responseHeader": { 
"zkConnected": true, 
"status": 0, 
"QTime": 60 
}, 
"response": { 
"numFound": 0, 
"start": 0, 
"docs": []

] 
}, 
"shoes", 
{

"startOffset": 5, 
"endOffset": 10, 
"origFreq": 0, 
"suggestion": [ 
{

}, 
{

"freq": 30 
}, 
{

"freq": 30 
}, 
{ 
"word": "s h o e s", 
"freq": 4 
}, 
{ 
"word": "sheer", 
"freq": 15 
}, 
{ 
"word": "sheen", 
"freq": 4 
}, 
{ 
"word": "sheet", 
"freq": 3 
}, 
{ 
"word": "shower", 
"freq": 2 
}, 
{ 
"word": "shock", 
"freq": 1 
}, 
{ 
"word": "shred", 
"freq": 1 
} 
] 
} 
], 
"correctlySpelled": false, 
"collations": [] 
} 
} 

如何設置的排序規則嗎？

Answer 1

讓我們先來看看文檔中定義爲SpellCheck Collate

Solr的原因基於在提交的查詢每個 項最佳建議建立一個新的查詢。

長話短說，當您指定spellcheck.collat​​e =真正發生的事情是，你問Solr的建議，你可以重新執行一個新的查詢，會比你收到的建議的組合更好。讓我給你看幾個例子。

• 比方說，你想搜索

初步審計

• 而不管出於什麼原因，它被輸入爲

initila AUD TI

• 隨着整理假，你會得到以下拼寫檢查建議

<lst name="suggestions"> 
     <lst name="initila"> 
      <int name="numFound">5</int> 
      <int name="startOffset">1</int> 
      <int name="endOffset">8</int> 
      <arr name="suggestion"> 
       <str>initial</str> 
       <str>initi la</str> 
       <str>initiala</str> 
       <str>ini tila</str> 
       <str>initilal</str> 
      </arr> 
     </lst> 
     <lst name="audt"> 
      <int name="numFound">4</int> 
      <int name="startOffset">9</int> 
      <int name="endOffset">13</int> 
      <arr name="suggestion"> 
       <str>aud t</str> 
       <str>audit</str> 
       <str>au dt</str> 
       <str>audi</str> 
      </arr> 
     </lst> 
    </lst> 

這意味着你將有每個字的若干建議

• 但如果你 打開排序規則，最有可能 - 如果有的話 - 建議應執行的查詢是什麼。它不能保證是最好的，雖然，認爲它是一個很好的猜測，可以幫助你

  <lst name="suggestions"> 
      <lst name="initila"> 
       <int name="numFound">5</int> 
       <int name="startOffset">1</int> 
       <int name="endOffset">8</int> 
       <arr name="suggestion"> 
        <str>initial</str> 
        <str>initi la</str> 
        <str>initiala</str> 
        <str>ini tila</str> 
        <str>initilal</str> 
       </arr> 
      </lst> 
      <lst name="audti"> 
       <int name="numFound">5</int> 
       <int name="startOffset">9</int> 
       <int name="endOffset">14</int> 
       <arr name="suggestion"> 
        <str>audit</str> 
        <str>audt i</str> 
        <str>auditi</str> 
        <str>au dti</str> 
        <str>audtis</str> 
       </arr> 
      </lst> 
      <lst name="collation"> 
       <str name="collationQuery">initial audit</str> 
       <int name="hits">1983</int> 
       <lst name="misspellingsAndCorrections"> 
        <str name="initila">initial</str> 
        <str name="audti">audit</str> 
       </lst> 
      </lst> 
  </lst> 
  

，這將是推薦的查詢

初步審計

這是從這裏獲得的

<str name="collationQuery">initial audit</str> 

和歸類僅如果在索引推薦的查詢，將滿足你在找什麼

Answer 2

以下方法解決我的問題的工作：

1. 下requestHandler添加默認字段爲defaults孩子列表即<str name="df">name_spell</str>。現在執行您的查詢將給出collations結果。這裏可以使用q或spellcheck.q中的任何一個。

OR

使用q代替spellcheck.q和同時使用q指定字段即代替spellcheck.q=nike%20shoes使用q=name_spell:(nike%20shoes)和它將使collations結果。
