Question

我正在使用Solr。我需要搜索与提供的关键字匹配的条目功能应该类似于％keyword％这样的SQL查询我的类型文件：text_en 我使用 face ，它正在获取数据为facebook（这是正确的）另外我还提取关键字喜欢“面对”（这是不正确的）。

我的想法是获取所有关键字，例如“％face％”

我该怎么做？我正在使用SOlr 4.4 我的solr架构如下：

<fieldType name="text_en" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <!-- 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.
        -->
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="lang/stopwords_en.txt"
                />
        <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.EnglishPossessiveFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
    <!-- Optionally you may want to use this less aggressive stemmer instead of PorterStemFilterFactory:
        <filter class="solr.EnglishMinimalStemFilterFactory"/>
    -->
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="lang/stopwords_en.txt"
                />
        <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.EnglishPossessiveFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
    <!-- Optionally you may want to use this less aggressive stemmer instead of PorterStemFilterFactory:
        <filter class="solr.EnglishMinimalStemFilterFactory"/>
    -->
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
    </fieldType>

Answer 1

如果您不想匹配“面对”，则应禁用词干。

相反，您可以使用EdgeNGramFilterFactory来索引单词的子字符串

<filter class="solr.EdgeNGramFilterFactory" minGramSize="3" maxGramSize="25" />

像使用text_en进行搜索一样
