Solr中的ToTitleCase停止Solr中的SCREAMING CAPS [英] ToTitleCase in solr to stop SCREAMING CAPS in Solr

问题描述

我正在使用solr的构面，但遇到了一个我希望可以使用滤镜解决的问题.

I'm using solr's faceting and i've run into a problem that i was hoping i could get around using filters.

基本上有些时候，城镇名称会以

Basically some times a town name will come through to SOLR as

剑桥"

有时它会以

剑桥"

我想在Solr中使用过滤器来停止城镇名称的SCREAMING CAPS版本.似乎所有文本都小写. >

I wanted to use a filter in Solr to stop the SCREAMING CAPS version of the town name. It seems there is a fitler to make all the text lower case.

<!-- A text field that only sorts out casing for faceting -->
    <fieldType name="text_facet" class="solr.TextField" positionIncrementGap="100">
      <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>

我想知道是否有人知道一个过滤器，该过滤器将忽略单词的第一个字符并将小写字母应用于其余字符.例如

I was wondering if anyone knew of a filter which will Ignore the First character of a word and apply lowercase to the rest of the characters. E.g.

• 剑桥>>剑桥
• 赫尔河畔金斯顿>>赫尔河畔金斯顿

等

或者，如果编写自己的过滤器很容易..在此方面的一些帮助将不胜感激..我不是Java语言的人.

Alternatively if it's easy to write your own filters.. some help on how to do that would be appreciated.. I'm not a Java person..

谢谢

推荐答案

AFAIK没有这样的内置过滤器.如果要编写，请参见

AFAIK there is no built-in filter like that. If you want to write it, see LowerCaseFilterFactory and LowerCaseFilter for reference, it doesn't seem to be very hard.

或者您可以执行此客户端操作，即在SolrNet中，您可以编写一个ISolrOperations装饰器，该装饰器使用

Or you could do this client-side, i.e. in SolrNet you could write a ISolrOperations decorator that does the necessary transformations after the real query, using ToTitleCase.
