Solr的 - 不区分大小写的搜索不工作(Solr - case-insensitive searc

2019-06-27 05:42发布

我想申请现场不区分大小写的搜索myfield Solr中。

我用Google搜索了一下是什么,以及我发现,我需要申请LowerCaseFilterFactory到字段类型和领域应该是solr.TextFeild

我申请了,在我的schema.xml并重新索引的数据,然后还我的搜索似乎是区分大小写的。

下面是我执行搜索。

http://localhost:8080/solr/select?q=myfield:"cloud university"&hl=on&hl.snippets=99&hl.fl=myfield

下面是定义字段类型

 <fieldType name="text_en_splitting" class="solr.TextField" positionIncrementGap="100" autoGeneratePhraseQueries="true">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <!-- in this example, we will only use synonyms at query time
        <filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
        -->
        <!-- Case insensitive stop word removal.
          add enablePositionIncrements=true in both the index and query
          analyzers to leave a 'gap' for more accurate phrase queries.
        -->
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords_en.txt"
                enablePositionIncrements="true"
                />
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords_en.txt"
                enablePositionIncrements="true"
                />
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
    </fieldType>

以下是我的字段定义

 <field name="myfield" type="text_en_splitting" indexed="true" stored="true" />

不知道,什么是错。 请帮我解决这个问题。

谢谢

Answer 1:

你应该把solr.LowerCaseFilterFactory字分隔符之前因为下端盖,反之亦然中间盖触发字分隔符



Answer 2:

我建议你应该使用分析工具,看表情是怎样的表达被索引以及如何搜索。 http://localhost:8983/solr/admin/analysis.jsp?highlight=on

我觉得可能是与WordDelimiterFilterFactory(它是在查询和索引不同)的问题,但是这只是一个猜测。

选择工具字段类型text_en_splitting和字段值指数进入ClOUD UNIVERSITY ,并在字段值查询cloud university 。 还要选择详细输出,看看你会得到什么。
