打開/關閉詞幹

Question

我已經修改schema.xml以具有兩個字段，一個用於詞幹，另一個用於無詞幹。我也使用複製字段將一個複製到另一個。最後在solrconfig.xml中添加了相應的dismax。這是需要完成的一切嗎？我有一種感覺我錯過了一些東西。通過SOLR管理面板測試它的最佳方式是什麼？還有另一種方法來測試它嗎？

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">

    <tokenizer class="solr.WhitespaceTokenizerFactory"/> 
    <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>

    <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.KeywordMarkerFilterFactory" protected="protwords.txt"/> 
    <filter class="solr.EnglishMinimalStemFilterFactory"/> 
    </analyzer> 
    <analyzer type="query"> 
    <charFilter class="solr.HTMLStripCharFilterFactory"/> 
    <tokenizer class="solr.WhitespaceTokenizerFactory"/> 
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> 
    <filter class="solr.StopFilterFactory"

</fieldType> 

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

Answer 1

要測試領域的詞幹，是的，你應該能夠做你需要的一切「字段分析「工具在管理面板上。 （點擊「分析」）。

在頂部，輸入您的字段名稱。 （contents_a）

提供一個測試值，您應該可以清楚地看到結果。

您可以檢查上半部分的「詳細」複選框，以便按順序獲取該字段上正在運行的過濾器的超詳細視圖。
