How to use solr

Please read document via http://www.ibm.com/developerworks/cn/opensource/os-php-apachesolr/ firstly

环境：

JDK 1.6
apache-solr-1.2.0 [http://lucene.apache.org/solr]
tomcat 5.5.17
xampp
SolrPhpClient 开发包 [https://issues.apache.org/jira/browse/SOLR-341]

1.安装solr

a)下载apache-solr-1.2.0.zip，解压。将apache-solr-1.2.0\dist 下的apache-solr-1.2.0.war 改名为solr.war并拷贝到tomcat目录下的webapps目录中。
b)将apache-solr-1.2.0\example\ 下的 solr 目录拷贝到任意位置，如：E:\solr
c) 在tomcat目录下的conf\Catalina\localhost 目录中（如果没有则手工创建该目录）创建solr.xml文件，文件内容如下：

<Context docBase="D:/tomcat/webapps/solr.war" debug="0" crossContext="true" >
    <Environment name="solr/home" type="java.lang.String" value="E:/solr" override="true" />
</Context>

d) 修改tomcat的server.xml文件，找到<Connector port="8080" … 项（假设tomcat监听8080端口），添加编码方式，修改后如下<Connector port="8080" URIEncoding="UTF-8" …
e) 启动tomcat。在浏览器中输入http://localhost:8080/solr/，出现“Welcom to Solr”页面，说明安装成功。

2.建立自定义索引模式

a) 打开E:\solr\conf\schema.xml 文件找到
<fields>
……
<fields>
替换为
<fields>
<field name="id" type="string" indexed="true" stored="true" required="true" />
<field name="name" type=" string " indexed="true" stored="true" required="true" />
<field name="address" type="text" indexed="true" stored="true" multiValued="true" required="true" />
</fields>

<defaultSearchField>text</defaultSearchField>
替换为
<defaultSearchField>name</defaultSearchField>

删除所有< copyField …> 项

3.建立PHP客户端
在wamp的www目录下建立solr目录。
将SolrPhpClient.zip解压，并将其中的Apache目录拷贝到www/solr目录下。

创建index.php文件，内容如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="zh-CN" lang="zh-CN">
<head>
<meta content="text/html; charset=UTF-8" http-equiv="Content-Type"/>
<title></title>
</head>
<body>
<?php
require_once( 'Apache/Solr/Service.php' );
$solr = new Apache_Solr_Service( '127.0.0.1', '8080', '/solr' );
if ( ! $solr->ping() ) {
    echo 'Solr service not responding.';
    exit;
}

$parts = array(
    'a' => array(
      'id' => 1,
      'name' => 'xxx',
      'address' => array( '111', '222' ),
    ),

    'b' => array(
      'partno' => 2,
      'name' => 'yyy',
      'model' => '3333',
    )
);

$documents = array();
foreach ( $parts as $item => $fields ) {
    $part = new Apache_Solr_Document();
    foreach ( $fields as $key => $value ) {
      if ( is_array( $value ) ) {
        foreach ( $value as $datum ) {
          $part->setMultiValue( $key, $datum );
        }
      }
      else {
        $part->$key = $value;
      }
    }
    $documents[] = $part;
}
try {
    $solr->addDocuments( $documents );
    $solr->commit();
    $solr->optimize();
}
catch ( Exception $e ) {
    echo $e->getMessage();
}
$offset = 0;
$limit = 10;
$queries = array(
    'id: 1 OR id: 2',
    'name: xxx',
    'name: 111'
);

foreach ( $queries as $query ) {
    $response = $solr->search( $query, $offset, $limit );
    if ( $response->getHttpStatus() == 200 ) {
      if ( $response->response->numFound > 0 ) {
        foreach ( $response->response->docs as $doc ) {
          echo "$doc->partno $doc->name <br />";
        }
        echo '<br />';
      }
    }
    else {
        echo $response->getHttpStatusMessage();
    }
}
?>
</body>
</html>
