Solr：Facet 没有创建任何输出

Question

我正在使用 Solr 4.4.0 和运行一些基本查询。这就是我在查询框中插入 title:* 时所做的

<?xml version="1.0" encoding="UTF-8"?>
<response>

<lst name="responseHeader">
  <int name="status">0</int>
  <int name="QTime">3</int>
  <lst name="params">
    <str name="q">title:*</str>
    <str name="indent">true</str>
    <str name="wt">xml</str>
    <str name="_">1430883449558</str>
  </lst>
</lst>
<result name="response" numFound="70" start="0">
  <doc>
    <str name="id">db01</str>
    <str name="isbn">1933988177</str>
    <str name="author">Michael McCandless, Erik Hatcher, Otis     Gospodnetic</str>
    <str name="author_s">Michael McCandless, Erik Hatcher, Otis Gospodnetic</str>
    <int name="numpages">475</int>
    <str name="description">When Lucene first hit the scene five years ago, it was nothing short of amazing. By using this open-source, highly scalable, super-fast search engine, developers could integrate search into applications quickly and efficiently. A lot has changed since then-search has grown from a "nice-to-have" feature into an indispensable part of most enterprise applications. Lucene now powers search in diverse companies including Akamai, Netflix, LinkedIn, Technorati, HotJobs, Epiphany, FedEx, Mayo Clinic, MIT, New Scientist Magazine, and many others.</str>

    <long name="_version_">1500385802538975232</long></doc>

以此类推70次...

这没关系，因为这是我想要的结果（70 本书），但是当我尝试添加 facet.field = publisher 时，它什么也没做。它 returns 与上面的输出完全相同。我怎样才能让这个方面工作？索引设置为 true 和一切。我究竟做错了什么？这是我的架构的摘录：

<field name="title" type="text_general" indexed="true" stored="true" multiValued="true"/>
<field name="subject" type="text_general" indexed="true" stored="true"/>
<field name="description" type="text_general" indexed="true" stored="true"/>
<field name="comments" type="text_general" indexed="true" stored="true"/>
<field name="author" type="text_general" indexed="true" stored="true"/>
<field name="keywords" type="text_general" indexed="true" stored="true"/>
<field name="category" type="text_general" indexed="true" stored="true"/>
<field name="resourcename" type="text_general" indexed="true" stored="true"/>
<field name="url" type="text_general" indexed="true" stored="true"/>
<field name="content_type" type="string" indexed="true" stored="true" multiValued="true"/>
<field name="last_modified" type="date" indexed="true" stored="true"/>
<field name="links" type="string" indexed="true" stored="true" multiValued="true"/>
<field name="yearpub" type="string" indexed="true" stored="true"/>
<field name="pubdate" type="date" indexed="true" stored="true"/>
<field name="publisher" type="text_general" indexed="true" stored="true"/>
<field name="numpages" type="int" indexed="true" stored="true"/>
<field name="isbn" type="text_general" indexed="true" stored="true"/>

Answer 1

您需要在使用 WhitespaceTokenizerFactory 的发布者字段上更改 text_general 意味着它拆分 phrases/strings 遇到空格时分成块。

<field name="publisher" type="text_general" indexed="true" stored="true"/>

所以剑桥大学出版社分为

剑桥
大学
按下

要么删除该分词器，要么使用其他不使用 WhitespaceTokenizerFactory[=17 的 fieldType =]

您可以使用 string 字段类型，因此请更新以下内容并重新启动 Solr 并重新索引数据

<field name="publisher" type="string" indexed="true" stored="true"/>
