为什么solr仅通过精确搜索返回结果? [英] Why is solr returning result with only exact search?

问题描述

我创建了一个核心，secondCore{id, resid, title, name, cat, role, exp} 考虑一个样本数据:{"id" : "11","resid" : 384,"title" : "perl and java developer","name" : "appnede new name","cat" : "22,11","role" : "new role","exp" : 1 }. 当我搜索title:perl时，我得到0个结果.仅当我搜索title:"perl and java developer"或title:perl*时，我才会得到提及的结果. 响应:

I have created a core, secondCore{id, resid, title, name, cat, role, exp} Consider a sample data: {"id" : "11","resid" : 384,"title" : "perl and java developer","name" : "appnede new name","cat" : "22,11","role" : "new role","exp" : 1 }. When I search for title:perl, I get 0 result. I get mentioned result, only if I search for title:"perl and java developer" or title:perl*. Response:

<response>

<lst name="responseHeader">
  <int name="status">0</int>
  <int name="QTime">2</int>
  <lst name="params">
    <str name="indent">true</str>
    <str name="q">title:perl*</str>
    <str name="_">1444371225114</str>
    <str name="wt">xml</str>
  </lst>
</lst>
<result name="response" numFound="1" start="0">
  <doc>
    <str name="id">11</str>
    <arr name="resid">
      <long>384</long>
    </arr>
    <arr name="title">
      <str>perl and java developer</str>
    </arr>
    <arr name="name">
      <str>appnede new name</str>
    </arr>
    <arr name="cat">
      <long>2211</long>
    </arr>
    <arr name="role">
      <str>new role</str>
    </arr>
    <arr name="exp">
      <long>1</long>
    </arr>
    <long name="_version_">1514531870450122752</long></doc>
</result>
</response>

此外，为什么响应在arr <arr name="role"><str>new role</str></arr>中?我想要在<str name="role">new role</str>中使用它，因此也需要其他文件.怎么做?我正在使用solr 5.3.0.

Also, why response is in arr <arr name="role"><str>new role</str></arr>? I want it in <str name="role">new role</str> and so with other fileds also. How to do? I'm using solr 5.3.0.

推荐答案

我认为您已将字段定义为字符串而不是文本.字符串字段确实匹配，而文本字段将为您提供所需的结果.

I think you have defined your field as string instead of text. String field does exact match whereas a text field will get you the results you are looking for.
