Question

我正在使用Solarium建议器来获取建议，我期望Hits部分从新单词返回一些命中但现在它返回：

    {
   "spellcheck":{
      "suggestions":[
         "pho",
         {
            "numFound":8,
            "startOffset":0,
            "endOffset":3,
            "suggestion":[
               "photo",
               "phone",
               "phone's",
               "phones",
               "photography",
               "photoimpression's",
               "photographers",
               "photos"
            ]
         },
         "collation",
         [
            "collationQuery",
            "photo",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photo"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "phone",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "phone"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "phone's",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "phone's"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "phones",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "phones"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photography",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photography"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photoimpression's",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photoimpression's"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photographers",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photographers"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photos",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photos"
            ]
         ]
      ]
   }
}

我的设置是：

<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.TSTLookupFactory</str>
        <str name="field">text</str>
        <float name="threshold">0.005</float>
        <str name="buildOnCommit">true</str>
    </lst>
</searchComponent>

对于我的组件和

<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">5</str>
        <str name="spellcheck.collate">true</str>
        <str name="spellcheck.maxCollations">10</str>
        <str name="spellcheck.collateExtendedResults">true</str>
    </lst>
    <arr name="components">
        <str>suggest</str>
    </arr>
</requestHandler>

关于如何填写这些内容的任何想法，以便我可以向最终用户展示#results？

Answer 1

将以下内容添加到SearchHandler配置中，然后您将获得每个归类hitcounts：

<str name="spellcheck.maxCollationTries">1</str>

注意：这将使整理程序通过使用它们执行实际查询来验证排序规则，从而生成hitcounts。为了使验证查询更快，他们已经禁用了评分和提升，并且也没有加载任何存储的字段，但是整理者仍然在每次整理时运行额外的查询 - 如果你有一个高maxCollations的话需要注意设置。

Answer 2

可能有点迟了......我遇到了同样的问题，直到我意识到我必须明确告诉Solr 运行查询，以便它可以返回命中数。

您的requestHandler需要QueryComponent个配置，默认配置名为“query”，只需将其添加到您的requestHandler的组件部分。

<arr name="components">
  <str>query</str>
  <str>suggest</str>
</arr>

注意：如果请求处理程序设置了defType param（指定要使用的查询解析器），则不需要这样做。

Solr建议总是返回0作为命中数
