autocomplete - Solr Suggester 是否支持中缀搜索？

Question

wiki page of the Solr Suggester component没有提到如何搜索提供的字段？仅是前缀，还是也可以进行中缀搜索？

Answer 1

是的，支持。编辑你的 solrconfig.xml，转到 searchComponent 元素，从 org.apache.solr.spelling.suggest.tst.TSTLookupFactory 更改“lookupImpl”的值(如 wiki page of the Solr Suggester component 示例所示，但它可以是另一个像 FuzzyLookupFactory 等.. .) 到 AnalyzingInfixLookupFactory。

它需要与此非常相似:

<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
 <str name="lookupImpl">AnalyzingInfixLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">yourSearchFieldName</str>
<str name="suggestAnalyzerFieldType">yourSearchFieldType(String, text-general)</str>
<str name="buildOnStartup">true</str>
</lst>
</searchComponent>

<requestHandler name="/suggest" class="solr.SearchHandler" 
              startup="lazy" >
<lst name="defaults">
  <str name="suggest">true</str>
  <str name="suggest.count">10</str>
</lst>
<arr name="components">
  <str>suggest</str>
</arr>
</requestHandler>

更改后不要忘记重新启动 solr。
