get solr autosuggest結果短語

我想使用solr爲搜索字段創建一個autosuggestion下拉菜單，但當我嘗試獲取短語的建議時，我陷入了困境。當我搜索「狗t」時，我想要得到一個結果集，其中包含諸如「狗處理」，「狗技巧」，「狗標記」等短語，但是我得到2個結果集，一個用於「狗」「（如‘狗’，‘狗骨頭’，‘狗’......），另一個是‘T’（如‘樹’的‘時間’......）get solr autosuggest結果短語

我查詢網址是：

http://localhost:8985/solr/mycollection/suggest?q=%22dog%20t%22&wt=json

和我的請求處理在solrconfig定義...

<searchComponent class="solr.SpellCheckComponent" name="suggest"> 
    <lst name="spellchecker"> 
     <str name="name">suggest</str> 
     <str name="classname">org.apache.solr.spelling.suggest.Suggester</str> 
     <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str> 
     <str name="field">suggest</str> <!-- the indexed field to derive suggestions from --> 
     <float name="threshold">0.0001</float> 
     <str name="buildOnCommit">true</str> 
    </lst> 
<str name="queryAnalyzerFieldType">textSuggest</str> 
    </searchComponent> 

    <requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest"> 
    <lst name="defaults"> 
     <str name="spellcheck">true</str> 
     <str name="spellcheck.dictionary">suggest</str> 
     <str name="spellcheck.onlyMorePopular">true</str> 
     <str name="spellcheck.count">10</str> 
    </lst> 
    <arr name="components"> 
     <str>suggest</str> 
    </arr> 
    </requestHandler>

的「建議」的字段類型的模式被定義爲

<fieldType name="textSuggest" class="solr.TextField" positionIncrementGap="100" > 
     <analyzer type="index"> 
<tokenizer class="solr.KeywordTokenizerFactory"/> 
    <filter class="solr.LowerCaseFilterFactory"/> 
<filter class="solr.ShingleFilterFactory" maxShingleSize="3" outputUnigrams="true" /> 
<filter class="solr.WordDelimiterFilterFactory" 
       generateWordParts="1" 
       generateNumberParts="1" 
       catenateWords="0" 
       catenateNumbers="0" 
       catenateAll="0" 
       preserveOriginal="1" splitOnCaseChange="1" 
       /> 
</analyzer> 
<analyzer type="query"> 
    <tokenizer class="solr.KeywordTokenizerFactory"/> 
    <filter class="solr.LowerCaseFilterFactory"/> 
</analyzer> 
    </fieldType>
