Solr没有正确搜索多值字段

Question

例如，在我们的模式中，我们有：

<field name="Key" type="int" indexed="true" stored="true" required="true"/>
<field name="_version_" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="Name" type="text_suggest_ngram" indexed="true" stored="true" required="false"/>
<field name="EmailAddress" type="text_email" indexed="true" stored="true" required="false"/>
<field name="Indexing" type="text_suggest_ngram" indexed="true" stored="true" multiValued="true"/>

大约有20个不同的领域。每个字段都复制到索引中：

<copyField source="Key" dest="Indexing"/>
<copyField source="Name" dest="Indexing"/>
<copyField source="EmailAddress" dest="Indexing"/>

为自定义域类型提供以下标记器：

<fieldType name="text_email" class="solr.TextField"/>

<fieldType name="text_suggest_ngram" class="solr.TextField" positionIncrementGap="100">
        <analyzer type="index">
            <tokenizer class="solr.UAX29URLEmailTokenizerFactory"/>
            <filter class="solr.LowerCaseFilterFactory"/>
            <filter class="solr.ASCIIFoldingFilterFactory"/>
            <filter class="solr.EnglishPossessiveFilterFactory"/>
            <filter class="solr.EdgeNGramFilterFactory" maxGramSize="20" minGramSize="2"/>
        </analyzer>
        <analyzer type="query">
            <tokenizer class="solr.UAX29URLEmailTokenizerFactory"/>
            <filter class="solr.LowerCaseFilterFactory"/>
            <filter class="solr.ASCIIFoldingFilterFactory"/>
            <filter class="solr.EnglishPossessiveFilterFactory"/>
        </analyzer>
</fieldType>

字段和内容都是从真实数据中编辑的，但它给出了想法。字段名称和内容都是较长的单词。这是取自SOLR管理搜索界面。

Answer 1

好的，所以我们的配置出现了两个错误。

1. EdgeNGramFilterFactory上的克大小为小

正如@Femtorgon指出的，克的大小是不正确的。增加克大小，然后修复完整的电子邮件地址搜索正确。如果我们搜索完整的电子邮件地址，Solr现在可以正确地找到文档。
