Solr：操纵查询字符串(Solr: manipulate query string)

 如何操作发送给Solr的查询字符串？ 
 
 例如，有人输入“stackoverflow-version1.0”，但没有找到结果。 但是，如果查询只是“stackoverflow”，那么搜索就会成功。 所以我想截断“ - ”并再次搜索第一部分。 
 
 一些研究将我带到了solr.PatternReplaceCharFilterFactory类。 我将它包含在我的schema.xml中，如下所示。 有谁看到，为什么我的查询仍然没有产生任何结果？ 我应该使用的其他课程？ 
 
 更新：现在我的代码如下所示： 
 
<fieldType name="ngram" class="solr.TextField" omitNorms="true">
  <analyzer type="index">
    <tokenizer class="solr.NGramTokenizerFactory" minGramSize="1" maxGramSize="20" />
    <filter class="solr.WordDelimiterFilterFactory"
      generateWordParts="1"
      splitOnNumerics="0"
      generateNumberParts="0"
      catenateWords="0"
      catenateNumbers="0"
      catenateAll="0"
      preserveOriginal="1"
    />
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.ASCIIFoldingFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.WordDelimiterFilterFactory"
      generateWordParts="1"
      generateNumberParts="0"
      splitOnNumerics="0"
      catenateWords="0"
      catenateNumbers="0"
      catenateAll="0"
      preserveOriginal="1"
    />
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.ASCIIFoldingFilterFactory"/>
  </analyzer>
</fieldType>
 
 运行分析仪它给了我这个：

How can I manipulate query strings that are sent to Solr? 
 
For example, someone enters "stackoverflow-version1.0" but there will be no results found. However if the query was only "stackoverflow" the search would have been successful. So I want to truncate at "-" and search again for the first part.
 
Some research brought me to the solr.PatternReplaceCharFilterFactory class. I included it as shown below in my schema.xml. Does anyone see, why my query still does not yield any results? Any other classes I should use?
 
UPDATE: Now my code looks like follows:
 
<fieldType name="ngram" class="solr.TextField" omitNorms="true">
  <analyzer type="index">
    <tokenizer class="solr.NGramTokenizerFactory" minGramSize="1" maxGramSize="20" />
    <filter class="solr.WordDelimiterFilterFactory"
      generateWordParts="1"
      splitOnNumerics="0"
      generateNumberParts="0"
      catenateWords="0"
      catenateNumbers="0"
      catenateAll="0"
      preserveOriginal="1"
    />
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.ASCIIFoldingFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.WordDelimiterFilterFactory"
      generateWordParts="1"
      generateNumberParts="0"
      splitOnNumerics="0"
      catenateWords="0"
      catenateNumbers="0"
      catenateAll="0"
      preserveOriginal="1"
    />
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.ASCIIFoldingFilterFactory"/>
  </analyzer>
</fieldType>
 
Running the analyzer it gives me this:
