Question

我是 Solr 的初学者，我的Soleserver索引中有以下集合：

{
        "id": "book5",
              "title": [
          "Five point someone"
        ],
        "author": "Chetan Bagat",
        "genere": "fantasy",
        "description": [
          "An iit guide"
        ],
        "comments": [
          "good",
          "excellent"
        ],
        "publications": [
          "swapnapublications",
          "pb publications"
        ]
      }

和

{
        "id": "book1",
        "title": [
          "nightatcallcenter"
        ],
        "author": "ChetanBagat",
        "genere": "fiction",
        "description": [
          "Aniitguide"
        ],
        "comments": [
          "good",
          "excellent"
        ],
        "publications": [
          "bangalorepublications",
          "aswinpublications"
        ]
      }

我的查询q =五点+点+某人失败

但我的查询

q = nightatcallcenter很好，为什么会这样？我怎样才能使第一个查询工作

我的架构：

 <fields>
        <field name="id" type="text_general" indexed="true" stored="true" required="true" multiValued="false" />
        <field name="title" type="text_general" indexed="true" stored="true" multiValued="true"/ 
            <field name="genere" type="text_general" indexed="true" stored="true"/>
            <field name="description" type="text_general" indexed="true" stored="true" multiValued="true"/>
            <field name="comments" type="text_general" indexed="true" stored="true" multiValued="true"/>
            <field name="author" type="text_general" indexed="true" stored="true" />
            <field name="publications" type="text_general" indexed="true" stored="true" multiValued="true" />
            <copyField  source='*' dest='fulltext'/>
            <field name='fulltext' type='text_general' multiValued='true '/>
 </fields>

Answer 1

您遇到的问题是，使用text_general时，您将创建一个令牌。当您搜索Five +point+someone时，您正在寻找三个令牌：

五
点
有人

您可以使用的干净解决方案是创建自定义text_general，如下所示：

<fieldType name="text_general" class="solr.TextField" positionIncrementGap="100">
  <analyzer type="index">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
</fieldType>

Answer 2

感谢@alexf，tockenizer完美运作

<fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" > <analyzer> <tokenizer class="solr.WhitespaceTokenizerFactory"/> </analyzer> </fieldType>

为什么Solr查询不能处理空格？
