如果文档中使用复数，而搜索文本中使用单数，则配置SOLR查找文档? [英] Configure SOLR to find documents if the plural is used in the document, and the singular in the search text?

问题描述

我用的是solr，设置在localhost:8983我基本上使用的是开箱即​​用的示例.我输入了一个名为Car"的文档，另一个名为Cars".

I am using solr, set up at localhost:8983 I am basically using the out of the box example. I have entered one document with a name "Car", and another with a name "Cars".

如果我访问任何一个:

http://localhost:8983/solr/select?q=Car

或

http://localhost:8983/solr/select?q=Cars

我希望得到这两个文件.目前，我没有.

I would expect to get both documents. At the moment, I don't.

在schema.xml"的fields标签中，name"的条目是:

In the fields tag of "schema.xml", the entry for "name" is:

text_general"具有以下分析器"(不含词干分析器):

"text_general" has the following "analyzers" (without the stemmers):

<analyzer type="index">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
    <filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    <filter class="solr.LowerCaseFilterFactory"/>
</analyzer>

我尝试为每个分析器添加一个词干分析器.我试过了:

I tried to add a stemmer to each analyzer. I tried:

<filter class="solr.PorterStemFilterFactory"/>
<filter class="solr.KStemFilterFactory"/>
<filter class="solr.EnglishMinimalStemFilterFactory"/>

这样做会使搜索汽车"会找到汽车"，但我永远找不到汽车".

Doing so makes it such that searching for "Cars" will find "Car", but I can never find "Cars".

应该可以找到汽车"吗?

Should it be possible to find "Cars"?

任何帮助将不胜感激.谢谢.

Any help would be greatly appreciated. Thank you.

推荐答案

是可以的，只需要在最后(LowerCaseFilterFactory 之后)添加 porter 过滤器:

It is possible, just add porter filter at the end (after LowerCaseFilterFactory):

<filter class="solr.SnowballPorterFilterFactory" language="English" />

如果没有特殊需要，我不会将分析器分为索引和查询时间.您的查询时间分析器看起来非常适合在这两种情况下使用它.

If there is no special need, I would not divide analyser to index and query time. Your query time analyser looks perfectly good to use it in both cases.
