搜索solr索引以查找串联单词

Question

我正在用两个类似用例挣扎。

这是我索引中的示例文档：

{
        "id":"E850AC8D844010AFA76203B390DD3135",
        "brand_txt_en":"Tom Ford",
        "catch_all":["Tom Ford",
          "FT 5163",
          "Tom Ford",
          "FT 5163",
          "DARK HAVANA"],
        "model_txt_en":"FT 5163",
        "brand_txt_en_split":"Tom Ford",
        "model_txt_en_split":"FT 5163",
        "color_txt_en":"DARK HAVANA",
        "material_s":"acetato",
        "gender_s":"uomo",
        "shape_s":"Wayfarer",
        "lens_s":"cerchiata",
        "modelkey_s":"86_1_FT 5163",
        "sales_i":0,
        "brand_s":"Tom Ford",
        "model_s":"FT 5163",
        "color_s":"DARK HAVANA",
        "_version_":1569456572504997895
}

查询： brand_txt_en_split：tomford

没有结果！

字段类型是Solr的默认一个：

<fieldType name="text_en_splitting" class="solr.TextField" autoGeneratePhraseQueries="true" positionIncrementGap="100">
    <analyzer type="index">
      <tokenizer class="solr.WhitespaceTokenizerFactory"/>
      <filter class="solr.StopFilterFactory" words="lang/stopwords_en.txt" ignoreCase="true"/>
      <filter class="solr.WordDelimiterFilterFactory" catenateNumbers="1" generateNumberParts="1" splitOnCaseChange="1" generateWordParts="1" catenateAll="0" catenateWords="1"/>
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
      <filter class="solr.PorterStemFilterFactory"/>
    </analyzer>
    <analyzer type="query">
      <tokenizer class="solr.WhitespaceTokenizerFactory"/>
      <filter class="solr.SynonymFilterFactory" expand="true" ignoreCase="true" synonyms="synonyms.txt"/>
      <filter class="solr.StopFilterFactory" words="lang/stopwords_en.txt" ignoreCase="true"/>
      <filter class="solr.WordDelimiterFilterFactory" catenateNumbers="0" generateNumberParts="1" splitOnCaseChange="1" generateWordParts="1" catenateAll="0" catenateWords="0"/>
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
      <filter class="solr.PorterStemFilterFactory"/>
    </analyzer>
  </fieldType>

我希望WordDelimiterFilterFactory通过串联单词来产生" tomford"令牌，但看起来这似乎没有预期的工作。

"反向"用例是：

{ 
   ...  "model_txt_en_split": "The Clubmaster", ...
}

我希望在此查询之后找到该文档：俱乐部主

我想我应该在后一种情况下使用Edgargram过滤器，但实际上无法做到这一点。

感谢您的帮助

WordDelimiterFilterFactory具有catenateWords和catenateAll。它可以在您拥有的地方工作：

catenateWords: (integer, default 0) If non-zero, maximal runs of word parts will be joined: "hot-spot-sensor's" -> "hotspotsensor"
catenateAll: (0/1, default 0) If non-zero, runs of word and number parts will be joined: "Zap-Master-9000" -> "ZapMaster9000"`

要删除单词之间的空间，请尝试以下过滤器。

<filter class="solr.PatternReplaceFilterFactory" pattern="(s+)" replacement="" replace="all" />

添加/更新schema.xml后。重新启动服务器并重新索引数据。

您可以为您的字段名称尝试以下fieldType。

<analyzer>
  <tokenizer class="solr.KeywordTokenizerFactory"/>
  <filter class="solr.EdgeNGramFilterFactory" minGramSize="4" maxGramSize="25"/>
</analyzer>

输入字符串："John Oliver W Clane"

tokenizer要过滤： "John Oliver W Clane"

输出令牌：

"John", "John ", "John O", "John Ol", "John Oli", "John Oli", "John Oliv", "John Olive", "John Oliver", "John Oliver ", "John Oliver W", "John Oliver W "
, "John Oliver W C", "John Oliver W Cl", "John Oliver W Cla", "John Oliver W Clan", "John Oliver W Clane".

还有另一个过滤器，您可以尝试相同。

<filter class="solr.NGramFilterFactory" minGramSize="4" maxGramSize="25"/>
