我使用SOLR的spellcheck组件来获取建议，并期望Hits部分返回新单词的一些匹配结果，但它在所有情况下都返回零个匹配结果：
{
"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>有什么想法，我可以得到这个填写，以便我可以显示#结果给最终用户？

可能有点晚了......我遇到了同样的问题，直到我意识到我必须显式地告诉Solr*运行*查询，这样它才能返回命中计数。
您的requestHandler需要一个
QueryComponent配置，默认的配置名为“query”，只需将其添加到您的requestHandler的 components 部分。注意：如果请求处理程序具有
defType参数集（指定要使用的查询解析器），则不需要执行此操作。7tofc5zh2#
将以下内容添加到SearchHandler配置中，然后您将获得每个排序规则的命中计数：
**注意：**这将使排序器通过使用排序规则执行 * 实际查询 * 来验证排序规则，从而产生命中计数。为了使验证查询更快，它们禁用了计分和提升，并且也不加载任何存储字段，但排序器仍会为每个排序规则运行额外的查询-如果您的
maxCollations设置较高，则需要注意这一点。jv2fixgn3#
默认情况下，查询组件是执行链的一部分，因此不需要显式声明。
设置为true，您将获得正确填充的numberOfHits和mispellingAndCorrections。
