无法删除 Solr 中的标点符号 [英] Can't remove punctuation in Solr
问题描述
我安装了 solr 来查询 Drupal 站点上的内容.许多标题字段在字符串的开头都有标点符号,因此当我按标题排序时,标点符号会出现在列表的顶部.
I have a solr install to query content on a Drupal site. Many of the title fields have punctuation at the start of the string and so when I sort by title the punctuation appears top of the list.
我想让 solr 在按标题排序时忽略标题,但我尝试过的所有解决方案都不起作用.
I would like to get solr to ignore the the title when sorting by title but none of the solutions I have tried work.
我对 solr 还很陌生,所以这可能是我做错了一些非常简单的事情......我不太了解 schema.xml 文件中发生的事情!
I am fairly new to solr and so it may be something really simple that I am doing wrong... I don't really understand much of what is going on in the schema.xml file!
标题字段在 solr 中称为标签,我在 solr.PatternReplaceFilterFactory 中尝试了各种方法,但都不起作用.
The title field is called label in solr and I have tried various methods in solr.PatternReplaceFilterFactory which do not work.
<field name="label" type="text" indexed="true" stored="true" termVectors="true" omitNorms="true"/>
<copyField source="label" dest="sort_label"/>

推荐答案
这是通过 WordDelimiterFilterFactory
完成的.设置 generateWordParts=1.
将此过滤器添加到您的
This is done with the WordDelimiterFilterFactory
. Set generateWordParts=1.
Add this filter to your
