打开/关闭词干

Question

我已经修改schema.xml以具有两个字段，一个用于词干，另一个用于无词干。我也使用复制字段将一个复制到另一个。最后在solrconfig.xml中添加了相应的dismax。这是需要完成的一切吗？我有一种感觉我错过了一些东西。通过SOLR管理面板测试它的最佳方式是什么？还有另一种方法来测试它吗？

solrconfig.xml中：

<requestHandler name="dismax" class="solr.SearchHandler" > 
    <lst name="defaults"> 
    <str name="defType">dismax</str> 
    <str name="echoParams">explicit</str> 
    </lst> 
</requestHandler> 

schema.xml中：

<field name="contents" type="text_general" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true"/> 
<field name="contents_a" type="text_en_splitting" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true"/> 

    <!-- A general text field that has reasonable, generic 
    cross-language defaults: it tokenizes with StandardTokenizer, 
removes stop words from case-insensitive "stopwords.txt" 
(empty by default), and down cases. At query time only, it 
also applies synonyms. --> 
    <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100"> 
    <analyzer type="index"> 
    <charFilter class="solr.HTMLStripCharFilterFactory"/> 
    <tokenizer class="solr.WhitespaceTokenizerFactory"/> 
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> 
    <!-- in this example, we will only use synonyms at query time 
    <filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/> 
    --> 
    <filter class="solr.LowerCaseFilterFactory"/> 
    </analyzer> 
    <analyzer type="query">

    <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.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/> 
    --> 
    <!-- Case insensitive stop word removal. 
     add enablePositionIncrements=true in both the index and query 
     analyzers to leave a 'gap' for more accurate phrase queries. 
    --> 
    <filter class="solr.StopFilterFactory" 
      ignoreCase="true" 
      words="stopwords_en.txt" 
      enablePositionIncrements="true" 
      /> 
    <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/> 
    <filter class="solr.LowerCaseFilterFactory"/>

    <filter class="solr.EnglishMinimalStemFilterFactory"/> 
    </analyzer> 
    <analyzer type="query"> 
    <charFilter class="solr.HTMLStripCharFilterFactory"/> 
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>

</fieldType> 

    <copyField source="contents" dest="contents_a"/>

要测试领域的词干，是的，你应该能够做你需要的一切“字段分析“工具在管理面板上。 （点击“分析”）。

在顶部，输入您的字段名称。 （contents_a）

提供一个测试值，您应该可以清楚地看到结果。

您可以检查上半部分的“详细”复选框，以便按顺序获取该字段上正在运行的过滤器的超详细视图。
