PHP擴展安裝

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


2. 在E盤新建文件夾命名為elastic,，拷貝composer.phar到
E:/elastic目錄下面


3. 打開命令行窗口，進入E:/elastic


4. 在命令行運行：
php composer.phar require elasticsearch/elasticsearch


5. 此時E:/elastic目錄下會出現一個vendor目錄，安裝成功


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

創建索引

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

插入索引數據

1. include(‘./vendor/autoload.php‘);
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名稱
4. $index[‘type’] = ‘ems_run_log’; //類型名稱
5. $index[‘id’] = 1 //不指定id，系統會自動生成唯一id
6. $index[‘body’] = array(
7. ‘mac’ => ‘fcd5d900beca‘,
8. ‘customer_id’ => 3,
9. ‘product_id’ => 5,
10. ‘version’ => 2
11. );
12. $elastic->index($index);

查詢

1. include(‘./vendor/autoload.php‘);
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名稱
4. $index[‘type’] = ‘ems_run_log’; //類型名稱
5. $index[‘body’][‘query’][‘match’][‘mac’] = ‘fcd5d900beca’;
6. $index[‘size’] = 10;
7. $index[‘from’] = 200;
8. $elastic->search($index);
11. 相當於sql語句：
12. select*from ems_run_log where mac=‘fcd5d900beca’
13. limit 200,10;<strong>
14. </strong>

1. include(‘./vendor/autoload.php‘);
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名稱
4. $index[‘type’] = ‘ems_run_log’; //類型名稱
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);
14. 相當於sql語句：
15. select*from ems_run_log where mac=‘fcd5d900beca’
16. and product_id = 20 limit 200,10;

1. include(‘./vendor/autoload.php‘);
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名稱
4. $index[‘type’] = ‘ems_run_log’; //類型名稱
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);
14. 當於sql語句：
15. select*from ems_run_log where mac=‘fcd5d900beca’
16. or product_id = 20 limit 200,10;

1. include(‘./vendor/autoload.php‘);
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名稱
4. $index[‘type’] = ‘ems_run_log’; //類型名稱
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);
14. 相當於sql語句：
15. select*from ems_run_log where mac!=‘fcd5d900beca’
16. and product_id != 20 limit 200,10;

1. include(‘./vendor/autoload.php‘);
2. $elastic = new Elasticsearch\Client();
3. $index[‘index’] = ‘log’; //索引名稱
4. $index[‘type’] = ‘ems_run_log’; //類型名稱
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);
13. 相當於sql語句：
14. select*from ems_run_log where id>=20
15. and id<30 limit 200,10;

刪除文檔

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