solr不区分大小写的排序不起作用 [英] solr case insensitive sort not working

问题描述

我在solr schema.xml中只有一个字段

I have one field in solr schema.xml

<field name="short_name" type="text_general" indexed="true" stored="true" required="false" />
    <field name="short_name_copy" type="string_ci" indexed="true" stored="true" required="false" />
   <copyField source="short_name" dest="short_name_copy"/>

和字段类型

<fieldType name="string_ci" class="solr.TextField" sortMissingLast="true" omitNorms="true">
    <analyzer type="query">
        <tokenizer class="solr.KeywordTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
</fieldType>

并且我在代码中设置了排序字段

and I have set sort field in my code

query.addSortField("short_name_copy", ORDER.asc);

但是当我获得搜索结果时，其不区分大小写.它首先给出所有驼峰案例的结果，然后给出所有小写字母

But When I get search result its not sorted case insensitive. It gives all camel case result first and then all lower case

如果我有短名

Banu

Ajay

anil

sudhir

尼罗什

类似于Ajay，Banu，Nilesh，anil，sudhir

It sorts like Ajay, Banu, Nilesh, anil, sudhir

有人可以告诉我这里有什么问题吗

Can anybody please tell me whats wrong here

(我的搜索字段是short_name)

(My search field is short_name)

推荐答案

这是因为您仅在查询时间内使用分析器.要执行您想做的事情，您必须使用类似以下内容的方法:

This is because you are using your analyzer only in query time. To do what you want to do, you have to use something like:

<fieldType name="string_ci" class="solr.TextField" sortMissingLast="true" omitNorms="true">
  <analyzer>
    <tokenizer class="solr.KeywordTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
</analyzer>

或类似的东西

<fieldType name="string_ci" class="solr.TextField" sortMissingLast="true" omitNorms="true">
  <analyzer type="index">
    <tokenizer class="solr.KeywordTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.KeywordTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
