单词中间的部分文本匹配

我正在尝试在solr中使用部分单词匹配。

所以我有这样的架构设置:

<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
  <analyzer type="index">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <!-- in this example, we will only use synonyms at query time
    <filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
    -->
    <!-- Case insensitive stop word removal.
         enablePositionIncrements=true ensures that a 'gap' is left to
         allow for accurate phrase queries.
    -->
    <filter class="solr.StopFilterFactory"
            ignoreCase="true"
            words="stopwords.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.EnglishPorterFilterFactory" protected="protwords.txt"/>
    <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
    <filter class="solr.NGramFilterFactory" minGramSize="2" maxGramSize="1000" side="front" />
    <filter class="solr.NGramFilterFactory" minGramSize="2" maxGramSize="1000" side="back" />
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
    <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/>
    <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
  </analyzer>
</fieldType>

<field name="key"     type="string" indexed="false" stored="true" required="true" />
<field name="uid"     type="string" indexed="true"  stored="true" required="true" />

<field name="organisationid"     type="string" indexed="true"  stored="true" required="false" />
<field name="organisationname" type="text" indexed="true" stored="true" required="false" />
<field name="organisationcleanname" type="text" indexed="true" stored="true" required="false" />

<field name="practiceareas"     type="string"    indexed="true"  stored="true" required="false" multiValued="true" />
<field name="subeditions"     type="string"    indexed="true"  stored="true" required="false" multiValued="true" />

我已将我想要的所有数据编入索引,并拥有一些组织名称,例如:

  • A Kings Name
  • 阻止我
  • 全部
  • King and Wood
  • 轻轻地嘲笑我

当我使用以下搜索进行搜索时:(organisationname:king OR organisationcleanname:king) AND practiceareas:20 轻轻地黑客攻击不会回到结果中(是的,其实践区域为20)。我是否错误地设置了NGram?
