php中运用elasticsearch（composer）

PHP扩展安装

1. 环境要求：PHP_VERSION >= 5.3.9，composer工具


2. 在E盘新建文件夹命名为elastic,，拷贝composer.phar到
     E:/elastic目录下面


3. 打开命令行窗口，进入E:/elastic


4. 在命令行运行：
      php composer.phar require elasticsearch/elasticsearch


5. 此时E:/elastic目录下会出现一个vendor目录，安装成功


6. 使用方法：
       require 'vendor/autoload.php'; 
      $client = new Elasticsearch\Client();

创建索引

include('./vendor/autoload.php');  $elastic = new Elasticsearch\Client();  $index[‘index’] = ‘log’;  //索引名称  $index[‘type’] = ‘ems_run_log’; //类型名称  $data[‘body’][‘settings’][‘number_of_shards’] = 5;  //主分片数量  $data[‘body’][‘settings’][‘number_of_replicas’] = 0; //从分片数量  $elastic->indices()->create($index);  

插入索引数据

include('./vendor/autoload.php');    $elastic = new Elasticsearch\Client();    $index[‘index’] = ‘log’; //索引名称    $index[‘type’] = ‘ems_run_log’; //类型名称    $index[‘id’] = 1   //不指定id，系统会自动生成唯一id    $index[‘body’] = array(        ‘mac’ => 'fcd5d900beca',        ‘customer_id’ => 3,        ‘product_id’ => 5,        ‘version’ => 2    );    $elastic->index($index);  

查询

include('./vendor/autoload.php');     $elastic = new Elasticsearch\Client();     $index[‘index’] = ‘log’; //索引名称     $index[‘type’] = ‘ems_run_log’; //类型名称     $index[‘body’][‘query’][‘match’][‘mac’] = ‘fcd5d900beca’;     $index[‘size’] = 10;     $index[‘from’] = 200;     $elastic->search($index);        相当于sql语句：     select*from ems_run_log where mac=‘fcd5d900beca’     limit 200,10;<strong>  </strong>  

include('./vendor/autoload.php');    $elastic = new Elasticsearch\Client();    $index[‘index’] = ‘log’; //索引名称    $index[‘type’] = ‘ems_run_log’; //类型名称    $index[‘body’][‘query’][‘bool’][‘must’] = array(          array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),          array(‘match’ => array(‘product_id’ => 20))         );    $index[‘size’] = 10;    $index[‘from’] = 200;    $elastic->search($index);       相当于sql语句：    select*from ems_run_log where mac=‘fcd5d900beca’    and product_id = 20 limit 200,10;  

include('./vendor/autoload.php');  $elastic = new Elasticsearch\Client();  $index[‘index’] = ‘log’; //索引名称  $index[‘type’] = ‘ems_run_log’; //类型名称  $index[‘body’][‘query’][‘bool’][‘should’] = array(        array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),        array(‘match’ => array(‘product_id’ => 20))       );  $index[‘size’] = 10;  $index[‘from’] = 200;  $elastic->search($index);      当于sql语句：  select*from ems_run_log where mac=‘fcd5d900beca’  or product_id = 20 limit 200,10;  

include('./vendor/autoload.php');   $elastic = new Elasticsearch\Client();   $index[‘index’] = ‘log’; //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $index[‘body’][‘query’][‘bool’][‘must_not’] = array(         array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),         array(‘match’ => array(‘product_id’ => 20))        );   $index[‘size’] = 10;   $index[‘from’] = 200;   $elastic->search($index);      相当于sql语句：   select*from ems_run_log where mac!=‘fcd5d900beca’   and product_id != 20 limit 200,10;  

include('./vendor/autoload.php');     $elastic = new Elasticsearch\Client();     $index[‘index’] = ‘log’; //索引名称     $index[‘type’] = ‘ems_run_log’; //类型名称     $index[‘body’][‘query’][‘range’] = array(         ‘id’ => array(‘gte’ => 20,’lt’ => 30);       );     $index[‘size’] = 10;     $index[‘from’] = 200;     $elastic->search($index);        相当于sql语句：     select*from ems_run_log where id>=20     and id<30  limit 200,10;
