从solr索引中删除电子邮件地址 [英] Remove email address from solr indexing

问题描述

例如，如果我有这样的电子邮件：[e-mail]，Solr索引单词foo和barcom。

我想删除这些单词，但我不知道该怎么做。我尝试修改在我的索引字段中添加此规则的配置文件schema.xml：

 < filter class =solr。 PatternReplaceFilterFactorypattern =（。*）@（。*）replacement =replace =all/> 
  

但是，它不起作用。

解决方案

您可以将令牌检测为电子邮件地址并使用

 < fieldType name =emailsclass =solr.TextFieldsortMissingLast = trueomitNorms =true> 
< analyzer> 
< tokenizer class =solr.UAX29URLEmailTokenizerFactory/> 
< filter class =solr.TypeTokenFilterFactorytypes =email_type.txtuseWhitelist =true/> 
< / analyzer> 
< / fieldType> 
  

When Solr build the index, it gets parts of email address.

For exemple, if i have an email like this : [e-mail], Solr indexes the words "foo" and "barcom".

I want to remove theses words but I don't know how to do this. I tried to modify the configuration file schema.xml adding this rule on my indexed field :

<filter class="solr.PatternReplaceFilterFactory" pattern=" (.*)@(.*) " replacement=" " replace="all"/>

However, it doesn't work.

解决方案

You can detect tokens as a e-mailaddress and blacklist them using

  <fieldType name="emails" class="solr.TextField" sortMissingLast="true" omitNorms="true">
  <analyzer>
    <tokenizer class="solr.UAX29URLEmailTokenizerFactory"/>
    <filter class="solr.TypeTokenFilterFactory" types="email_type.txt" useWhitelist="true"/>
  </analyzer>
</fieldType>
