PHP 中运用 elasticsearch

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

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

插入索引数据

1. include('./vendor/autoload.php');
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名称
4. $index[‘type’] = ‘ems_run_log’; //类型名称
5. $index[‘id’] = 1 //不指定id，系统会自动生成唯一id
6. $index[‘body’] = array(
7. ‘mac’ => 'fcd5d900beca',
8. ‘customer_id’ => 3,
9. ‘product_id’ => 5,
10. ‘version’ => 2
11. );
12. $elastic->index($index);

查询

1. include('./vendor/autoload.php');
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名称
4. $index[‘type’] = ‘ems_run_log’; //类型名称
5. $index[‘body’][‘query’][‘match’][‘mac’] = ‘fcd5d900beca’;
6. $index[‘size’] = 10;
7. $index[‘from’] = 200;
8. $elastic->search($index);

相当于sql语句：
select*from ems_run_log where mac=‘fcd5d900beca’ limit 200,10;

1. include('./vendor/autoload.php');
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名称
4. $index[‘type’] = ‘ems_run_log’; //类型名称
5. $index[‘body’][‘query’][‘bool’][‘must’] = array(
6. array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),
7. array(‘match’ => array(‘product_id’ => 20))
8. );
9. $index[‘size’] = 10;
10. $index[‘from’] = 200;
11. $elastic->search($index);

相当于sql语句：
select*from ems_run_log where mac=‘fcd5d900beca’ and product_id = 20 limit 200,10;

1. include('./vendor/autoload.php');
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名称
4. $index[‘type’] = ‘ems_run_log’; //类型名称
5. $index[‘body’][‘query’][‘bool’][‘should’] = array(
6. array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),
7. array(‘match’ => array(‘product_id’ => 20))
8. );
9. $index[‘size’] = 10;
10. $index[‘from’] = 200;
11. $elastic->search($index);

当于sql语句：
select*from ems_run_log where mac=‘fcd5d900beca’ or product_id = 20 limit 200,10;

1. include('./vendor/autoload.php');
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名称
4. $index[‘type’] = ‘ems_run_log’; //类型名称
5. $index[‘body’][‘query’][‘bool’][‘must_not’] = array(
6. array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),
7. array(‘match’ => array(‘product_id’ => 20))
8. );
9. $index[‘size’] = 10;
10. $index[‘from’] = 200;
11. $elastic->search($index);

相当于sql语句：
select*from ems_run_log where mac!=‘fcd5d900beca’ and product_id != 20 limit 200,10;

1. include('./vendor/autoload.php');
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名称
4. $index[‘type’] = ‘ems_run_log’; //类型名称
5. $index[‘body’][‘query’][‘range’] = array(
6. ‘id’ => array(‘gte’ => 20,’lt’ => 30);
7. );
8. $index[‘size’] = 10;
9. $index[‘from’] = 200;
10. $elastic->search($index);

相当于sql语句：
select*from ems_run_log where id>=20 and id<30 limit 200,10;

删除文档

1. <pre name="code" class="php">include('./vendor/autoload.php');
2. $elastic = new Elasticsearch\Client();
3. $index['index'] = 'test'; //索引名称
4. $index['type'] = 'ems_test'; //类型名称
5. $index['id'] = 2;
6. $elastic->delete($index);
