我是Solr的新手,我按照一些教程来设置它。我正在使用Postgresql。当我跑http://localhost:8080/solr/select?q=*:*
时,我回来了:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">7</int>
<lst name="params">
<str name="q">*:*</str>
</lst></lst>
<result name="response" numFound="56" start="0">
<doc>
<str name="id">1</str>
</doc>
<doc>
<str name="id">2</str>
</doc>
...
...
<doc>
<str name="id">10</str>
</doc>
</result>
</response>
我希望得到一个包含first_name和last_name的子列表。
requestHandler
中的solrconfig.xml
:
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
我的data-config.xml
:
<dataConfig>
<dataSource type="JdbcDataSource"
driver="org.postgresql.Driver"
name="ds1" url="jdbc:postgresql://localhost/some_db" user="db_user" password="hatpants" />
<document name="kids">
<entity name="kid" pk="ID" dataSource="ds1"
query="select id,first_name,last_name from kid">
<field column="ID" name="id" indexed="true" />
<field column="FIRST_NAME" name="first_name" indexed="true" />
<field column="LAST_NAME" name="last_name" indexed="true" />
</entity>
</document>
</dataConfig>
当我运行数据导入时:http://localhost:8080/solr/dataimport?command=full-import
我明白了:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">4</int>
</lst>
<lst name="initArgs">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst></lst>
<str name="command">full-import</str>
<str name="status">idle</str>
<str name="importResponse"/>
<lst name="statusMessages">
<str name="Total Requests made to DataSource">1</str>
<str name="Total Rows Fetched">56</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2014-01-04 04:47:14</str>
<str name="">Indexing completed. Added/Updated: 56 documents. Deleted 0 documents.</str>
<str name="Committed">2014-01-04 04:47:14</str>
<str name="Optimized">2014-01-04 04:47:14</str>
<str name="Total Documents Processed">56</str>
<str name="Time taken ">0:0:0.243</str>
</lst>
<str name="WARNING">This response format is experimental. It is likely to change in the future.</str>
</response>
在我看来它能够连接到数据库。我在db中总共有56条记录。当我进行特定选择时,它不会返回任何结果。
答案 0 :(得分:1)
我明白了。
我需要将这些字段添加到我的schema.xml
文件中的字段部分。
<field name="first_name" type="text" indexed="true" stored="true" multiValued="true" />
<field name="last_name" type="text" indexed="true" stored="true" multiValued="true" />
和
<copyField source="first_name" dest="text"/>
<copyField source="last_name" dest="text"/>
