搜索字符串类型字段时遇到问题 [英] Facing issue while searching on string type field

问题描述

我在 Solr 搜索中遇到问题.我的架构如下

I am facing issue in Solr search. My schema is as follows

<fieldType name="c_text" class="solr.TextField">
<analyzer type="index">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
<field name="parentId" type="string" indexed="true" stored="true"/>
<field name="data_s" type="c_text" indexed="true" stored="true"/>
<field name="email" type="string" indexed="true" stored="true"/>
<field name="receivedDate" type="tdate" indexed="true" stored="true"/>

我正在搜索电子邮件字段.其中包含以下格式的数据
Tarun Nagpal

I am searching on email field. which contains the data in following format
Tarun Nagpal <[e-mail]>

//This is working fine
email:*tarun*

但是下面没有结果

email:"Tarun Nagpal"

你能帮忙吗，为什么它不像在电子邮件字段中搜索那样搜索词组.在 data_s 字段上搜索工作正常.

Can you please help, why it is not searching phrase like search on email field. Search on data_s field is working fine.

推荐答案

您需要使用文本字段类型，因为您打算搜索标记:

You need to use the text field type since you intend to search the tokens:

针对Tarun Nagpal :

string 字段将回答 == 等式和通配符查询，例如 *un Nagp*、*[e-mail]> 甚至更明显的奇特查询.

A string field will answer == equality and wildcard queries like *un Nagp*, *[e-mail]> and even more apparently exotic queries.

text 字段将回答标记 tarun、nagpal、tarunn abc 和 com.

A text field will answer to the tokens tarun, nagpal, tarunn abc and com.

其他实现 N-gram 和 Soundex 的字段类型甚至可以纠正您的拼写.

Other field types implementing N-gram and Soundex can even correct your spelling.
