PHP中使用Elasticsearch的方法

PHP中使用Elasticsearch

composer require elasticsearch/elasticsearch

会自动加载合适的版本！我的php是5.6的，它会自动加载5.3的elasticsearch版本！

Using version ^5.3 for elasticsearch/elasticsearch./composer.json has been updatedLoading composer repositories with package informationUpdating dependencies (including require-dev)Package operations: 4 installs, 0 updates, 0 removals - Installing react/promise (v2.7.0): Downloading (100%)  - Installing guzzlehttp/streams (3.0.0): Downloading (100%)  - Installing guzzlehttp/ringphp (1.1.0): Downloading (100%)  - Installing elasticsearch/elasticsearch (v5.3.2): Downloading (100%) Writing lock fileGenerating autoload files

简单使用

 ?phphtml' target='_blank'>class MyElasticSearch private $es; // 构造函数 public function __construct() include( ../vendor/autoload.php  $params = array( 127.0.0.1:9200  $this- es = /Elasticsearch/ClientBuilder::create()- setHosts($params)- build(); public function search() { $params = [ index = megacorp , type = employee , body = [ query = [ constant_score = [ //非评分模式执行 filter = [ //过滤器，不会计算相关度，速度快 term = [ //精确查找，不支持多个条件 about = 谭  $res = $this- es- search($params); print_r($res);}

 ?phprequire ./MyElasticSearch.php $es = new MyElasticSearch();$es- search();

执行结果

Array [took] = 2 [timed_out] =  [_shards] = Array [total] = 5 [successful] = 5 [skipped] = 0 [failed] = 0 [hits] = Array [total] = 1 [max_score] = 1 [hits] = Array [0] = Array [_index] = megacorp [_type] = employee [_id] = 3 [_score] = 1 [_source] = Array [first_name] = 李 [last_name] = 四 [age] = 24 [about] = 一个PHP程序员，热爱编程，谭康很帅，充满激情。 [interests] = Array [0] = 英雄联盟)

下面是官方的一些样例：

require ../vendor/autoload.php use Elasticsearch/ClientBuilder;$client = ClientBuilder::create()- build();

增加配置

$hosts = [ 127.0.01:9200 , // IP + Port$client = ClientBuilder::create() // Instantiate a new ClientBuilder- setHosts($hosts) // Set the hosts- build(); // Build the client object

或

$hosts = [ 127.0.01:9200 , // IP + Port$clientBuilder = ClientBuilder::create(); // Instantiate a new ClientBuilder$clientBuilder- setHosts($hosts); // Set the hosts$client = $clientBuilder- build(); // Build the client object

// Index 一个文档$params = [ index = my_index , type = my_type , id = my_id , body = [ testField = abc ]$response = $client- index($params);print_r($response);

$params = [ index = my_index , type = my_type , id = my_id $response = $client- get($params);print_r($response);

$params = [ index = my_index , type = my_type , body = [ query = [ match = [ testField = abc $response = $client- search($params);print_r($response);

$params = [ index = my_index , type = my_type , id = my_id $response = $client- delete($params);print_r($response);

结果如下

Array [_index] = my_index [_type] = my_type [_id] = my_id [_version] = 3 [result] = deleted [_shards] = Array [total] = 2 [successful] = 1 [failed] = 0 [_seq_no] = 2 [_primary_term] = 1)

$deleteParams = [ index = my_index $response = $client- indices()- delete($deleteParams);print_r($response);

$params = [ index = my_index , body = [ settings = [ number_of_shards = 2, number_of_replicas = 0$response = $client- indices()- create($params);print_r($response);
