我更改了schema.xml文件并添加了几个字段,就像这样
<field name="url" type="string" indexed="true" stored="true" />
<field name="content_type" type="text" indexed="true" stored="true" />
<field name="title" type="text" indexed="true" stored="true" />
<field name="keywords" type="text" indexed="true" stored="true" multiValued="true" />
<field name="text" type="text" indexed="true" stored="true" />
<field name="timestamp" type="text" indexed="true" stored="true" />
<field name="public" type="text" indexed="true" stored="true" multiValued="true" />
<field name="groups" type="text" indexed="true" stored="true" multiValued="true" />
<field name="sitename" type="text" indexed="true" stored="true" />
<field name="context" type="text" indexed="true" stored="true" />
<field name="modified_date" type="text" indexed="true" stored="true" />
因此,对应于这些字段,我创建了一个xml文件,并在其中添加了一些虚拟数据。
<add><doc>
<field name="url">http://www.host.com/</field>
<field name="content_type">text/html</field>
<field name="title">Testing Data</field>
<field name="keywords">software</field>
<field name="keywords">software_cycle</field>
<field name="text">search</field>
<field name="timestamp">2006-02-13T15:26:37Z</field>
<field name="public">Optimized</field>
<field name="public">Optimized_data</field>
<field name="groups">Standards</field>
<field name="groups">Standards_data</field>
<field name="sitename">GoInfo</field>
<field name="context">Scalability</field>
<field name="modified_date">2010-11-13T15:26:37Z</field>
</doc></add>
当我尝试将数据重新索引到solr时,如下所示: -
C:\apache-solr-3.2.0\example\exampledocs>java -Durl=http://localhost:7788/solr/u
pdate -jar post.jar *.xml
SimplePostTool: version 1.3
SimplePostTool: POSTing files to http://localhost:7788/solr/update..
SimplePostTool: POSTing file 30-example.xml
SimplePostTool: POSTing file hd.xml
SimplePostTool: POSTing file other.xml
SimplePostTool: FATAL: Solr returned an error #400 Bad Request
我总是在text.xml文件后出错,如果我删除了这个text.xml文件,那么我没有收到任何错误。如果我包含text.xml文件,这就是我得到的以下错误。任何帮助将不胜感激。

答案 0 :(得分:2)
你说你添加了一些字段(据说是示例模式),但你没有提到已经存在的字段发生了什么。我猜你在那里留下了先前存在的字段,这意味着id
仍然是必填字段(请参阅示例模式中的here),因此您看到错误。

“主键”ID。这确实是必需的。
