1、首先在MySQL中创建表,并写入数据
2、修改apache-solr-3.3.0\example\solr\conf\schema.xml文件
3、编辑apache-solr-3.3.0\example\solr\conf\solrconfig.xml文件,添加内容如下:
4、创建data-config.xml文件,放在apache-solr-3.3.0\example\solr\conf\目录下,文件内容如下:
5、将MySQL的JDBC驱动放在apache-solr-3.3.0\example\lib目录下
6、启动Solr服务,命令行进入apache-solr-3.3.0\example\目录,运行 java -jar start.jar
出现问题:
解决:
修改apache-solr-3.3.0\example\solr\conf\solrconfig.xml文件,删除内容如下:
wiki上的解释:
我的理解:相当于竞价排名,无视搜索的排序,可以额外在顶部配置自定义的结果
7、运行命令:在浏览器中输入:http://localhost:8983/solr/dataimport?command=full-import 来完成全量数据导入,在每次全量数据导入执行的时候,原有索引会被删除,如果不想删除原有索引,可以运行如下命令:http://localhost:8983/solr/dataimport?command=full-import&clean=false ,全量数据导入在浏览器中显示的效果如下:
8、进行搜索,在浏览器中输入http://localhost:8983/solr/admin/
搜索结果如下:
9、以不同的名字索引域
上面data-config.xml配置中mysql中表的名字和schema.xml索引的名字相同,也可以配置使用不同的名字,如下:
此时,solr_id, solr_name,solr_desc将被写到solr域中,务必注意要在schema.xml文件中配置好这些域
10、从多个表索引数据到Solr
修改data-config.xml文件
注意:schema.xml中还应该有solr_details域

1、首先在MySQL中创建表,并写入数据
-- ---------------------------- -- Table structure for course -- ---------------------------- CREATE TABLE `course` ( `id` int(11) NOT NULL, `user` varchar(20) NOT NULL, `title` varchar(50) NOT NULL, `content` varchar(200) NOT NULL, `time` datetime NOT NULL DEFAULT '0000-00-00 00:00:00', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ---------------------------- -- Records -- ---------------------------- INSERT INTO `course` VALUES ('1', 'tiehong', '搜索', '这一小节讲搜索引擎,可以通过搜索引擎查找一些数据', '2011-08-18 10:41:35'); INSERT INTO `course` VALUES ('2', '*', '存储', '这一小节讲分布式存储,可以存储很多数据', '2011-08-18 10:42:19'); INSERT INTO `course` VALUES ('3', 'lengda', '数据导入', '这一小节讲数据导入,可以从mysql数据库中导入数据', '2011-08-18 10:42:59');
2、修改apache-solr-3.3.0\example\solr\conf\schema.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <schema name="example" version="1.4"> <types> <fieldType name="tint" class="solr.TrieIntField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/> <fieldType name="string" class="solr.StrField" sortMissingLast="true" omitNorms="true"/> <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> </fieldType> <fieldType name="date" class="solr.TrieDateField" omitNorms="true" precisionStep="0" positionIncrementGap="0"/> </types> <fields> <field name="id" type="tint" indexed="true" stored="true" required="true" /> <field name="user" type="string" indexed="true" stored="true"/> <field name="title" type="text" indexed="true" stored="true"/> <field name="content" type="text" indexed="true" stored="true" /> <field name="time" type="date" indexed="true" stored="true" default="NOW"/> </fields> <uniqueKey>id</uniqueKey> <defaultSearchField>title</defaultSearchField> <solrQueryParser defaultOperator="AND"/> </schema>
3、编辑apache-solr-3.3.0\example\solr\conf\solrconfig.xml文件,添加内容如下:
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">data-config.xml</str> </lst> </requestHandler>
4、创建data-config.xml文件,放在apache-solr-3.3.0\example\solr\conf\目录下,文件内容如下:
<dataConfig> <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/dbname" user="user-name" password="password"/> <document> <entity name="id" query="select * from course"> </entity> </document> </dataConfig>
5、将MySQL的JDBC驱动放在apache-solr-3.3.0\example\lib目录下
6、启动Solr服务,命令行进入apache-solr-3.3.0\example\目录,运行 java -jar start.jar
出现问题:
严重: org.apache.solr.common.SolrException: QueryElevationComponent requires the schema to have a uniqueKeyField implemented using StrField at org.apache.solr.handler.component.QueryElevationComponent.inform(QueryElevationComponent.java:158) at org.apache.solr.core.SolrResourceLoader.inform(SolrResourceLoader.java:522) at org.apache.solr.core.SolrCore.<init>(SolrCore.java:594) at org.apache.solr.core.CoreContainer.create(CoreContainer.java:463) at org.apache.solr.core.CoreContainer.load(CoreContainer.java:316) at org.apache.solr.core.CoreContainer.load(CoreContainer.java:207) at org.apache.solr.core.CoreContainer$Initializer.initialize(CoreContainer.java:130) at org.apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java:94) at org.mortbay.jetty.servlet.FilterHolder.doStart(FilterHolder.java:97) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at org.mortbay.jetty.servlet.ServletHandler.initialize(ServletHandler.java:713) at org.mortbay.jetty.servlet.Context.startContext(Context.java:140) at org.mortbay.jetty.webapp.WebAppContext.startContext(WebAppContext.java:1282) at org.mortbay.jetty.handler.ContextHandler.doStart(ContextHandler.java:518) at org.mortbay.jetty.webapp.WebAppContext.doStart(WebAppContext.java:499) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerCollection.doStart(HandlerCollection.java:152) at org.mortbay.jetty.handler.ContextHandlerCollection.doStart(ContextHandlerCollection.java:156) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerCollection.doStart(HandlerCollection.java:152) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerWrapper.doStart(HandlerWrapper.java:130) at org.mortbay.jetty.Server.doStart(Server.java:224) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at org.mortbay.xml.XmlConfiguration.main(XmlConfiguration.java:985) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.mortbay.start.Main.invokeMain(Main.java:194) at org.mortbay.start.Main.start(Main.java:534) at org.mortbay.start.Main.start(Main.java:441) at org.mortbay.start.Main.main(Main.java:119)
解决:
修改apache-solr-3.3.0\example\solr\conf\solrconfig.xml文件,删除内容如下:
<!-- Query Elevation Component http://wiki.apache.org/solr/QueryElevationComponent a search component that enables you to configure the top results for a given query regardless of the normal lucene scoring. --> <searchComponent name="elevator" class="solr.QueryElevationComponent" > <!-- pick a fieldType to analyze queries --> <str name="queryFieldType">string</str> <str name="config-file">elevate.xml</str> </searchComponent> <!-- A request handler for demonstrating the elevator component --> <requestHandler name="/elevate" class="solr.SearchHandler" startup="lazy"> <lst name="defaults"> <str name="echoParams">explicit</str> </lst> <arr name="last-components"> <str>elevator</str> </arr> </requestHandler>
wiki上的解释:
引用
The QueryElevationComponent enables you to configure the top results for a given query regardless of the normal lucene scoring. This is sometimes called "sponsored search", "editorial boosting" or "best bets". This component matches the user query text to a configured Map of top results. Although this component will work with any QueryParser, it makes the most sense to use with DisMax style queries.
我的理解:相当于竞价排名,无视搜索的排序,可以额外在顶部配置自定义的结果
7、运行命令:在浏览器中输入:http://localhost:8983/solr/dataimport?command=full-import 来完成全量数据导入,在每次全量数据导入执行的时候,原有索引会被删除,如果不想删除原有索引,可以运行如下命令:http://localhost:8983/solr/dataimport?command=full-import&clean=false ,全量数据导入在浏览器中显示的效果如下:
This XML file does not appear to have any style information associated with it. The document tree is shown below. <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">5</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="WARNING"> This response format is experimental. It is likely to change in the future. </str> </response>
8、进行搜索,在浏览器中输入http://localhost:8983/solr/admin/
搜索结果如下:
This XML file does not appear to have any style information associated with it. The document tree is shown below. <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">0</int> <lst name="params"> <str name="indent">on</str> <str name="start">0</str> <str name="q">*:*</str> <str name="version">2.2</str> <str name="rows">10</str> </lst> </lst> <result name="response" numFound="3" start="0"> <doc> <str name="content">这一小节讲搜索引擎,可以通过搜索引擎查找一些数据</str> <int name="id">1</int> <date name="time">2011-08-18T02:41:35Z</date> <str name="title">搜索</str> <str name="user">tiehong</str> </doc> <doc> <str name="content">这一小节讲分布式存储,可以存储很多数据</str> <int name="id">2</int> <date name="time">2011-08-18T02:42:19Z</date> <str name="title">存储</str> <str name="user">*</str> </doc> <doc> <str name="content">这一小节讲数据导入,可以从mysql数据库中导入数据</str> <int name="id">3</int> <date name="time">2011-08-18T02:42:59Z</date> <str name="title">数据导入</str> <str name="user">lengda</str> </doc> </result> </response>
9、以不同的名字索引域
上面data-config.xml配置中mysql中表的名字和schema.xml索引的名字相同,也可以配置使用不同的名字,如下:
<dataConfig> <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/dbname" user="user-name" password="password"/> <document> <entity name="id" query="select id,name,desc from mytable"> <field column="id" name="solr_id"/> <field column="name" name="solr_name"/> <field column="desc" name="solr_desc"/> </entity> </document> </dataConfig>
此时,solr_id, solr_name,solr_desc将被写到solr域中,务必注意要在schema.xml文件中配置好这些域
10、从多个表索引数据到Solr
修改data-config.xml文件
<dataConfig> <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/dbname" user="user-name" password="password"/> <document> <entity name="outer" query="select id,name,desc from mytable"> <field column="id" name="solr_id"/> <field column="name" name="solr_name"/> <field column="desc" name="solr_desc"/> <entity name="inner" query="select details from another_table where id ='${outer.id}'"> <field column="details" name="solr_details"/> </entity> </entity> </document> </dataConfig>
注意:schema.xml中还应该有solr_details域
