• solr的增删改查


    solr的配置请查看:http://www.cnblogs.com/byteworld/p/5898651.html

    创建Core:(可以复制模版到solrhome estconf文件夹中)

    简化了(schema.xml配置文件)

    <?xml version="1.0" encoding="UTF-8" ?>
    <schema name="test_solr" version="1.5"> 
        <!--版本这个也需要加-->
        <field name="_version_" type="long" indexed="true" stored="true"/>
        <field name="_root_" type="string" indexed="true" stored="false"/>
    	<field name="id" type="string" stored="true" indexed="true"/>
    	<field name="name" type="string" stored="true" indexed="true" omitNorms="false"/>
    	<field name="price" type="string" stored="true" indexed="true"/>  
    	<fieldType name="string" class="solr.StrField" sortMissingLast="true" />
    	<!-- 这个主键必须加不然报错 -->
    	<uniqueKey>id</uniqueKey>
        <!-- boolean type: "true" or "false" -->
        <fieldType name="boolean" class="solr.BoolField" sortMissingLast="true"/>
