Elasticsearch全文搜索引擎-PHP使用教程
用Composer来生成php版的elasticsearch框架：
如果你还没有安装Composer的话请看：Composer安装教程文章。
1、声明依赖关系：
比方说，你的项目中需要一个php版的elasticsearch框架。为了将它添加到你的项目中（下载），你所需要做的就是创建一个 composer.json 文件，其中描述了项目的依赖关系。注意文件要放在你执行composer命令的目录中
{
"require":{
"elasticsearch/elasticsearch":"~2.0"
}
}2、cmd切换到要下载elasticsearch框架的目录，然后执行命令：composer install
如有出错误信息：
[Composer\Downloader\TransportException]
Content-Length mismatch, received 583439 bytes out of the expected 1215108
解决办法：切换国内镜像地址，再执行操作
1、通过命令切换如下：（最终修改的是composer.json）
composer config -g repo.packagist composer https://packagist.phpcomposer.com
2、直接修改 composer.json （其实跟方法1是一样的。）
{
"require":{
"elasticsearch/elasticsearch":"~2.0"
},
"repositories": {
"packagist": {
"type": "composer",
"url": "https://packagist.phpcomposer.com"
}
}
}
PHP使用elasticsearch教程：
下面我们讲一下基本使用方法，需要获取更多使用教程和方法请看官方文档：https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/_overview.html
想直接通过文件查看其他方法可以打开以下文件查看（基本使用的方法都在里面）：
1、\elasticsearch\src\Elasticsearch\Client.php中的方法
2、\elasticsearch\Namespaces\IndicesNamespace.php中的方法
ThinkPHP中的模型：

}其他形式用法测试：

$conn = get_conn();

$rtn = $stmt->fetchAll();
//delete index which already created
$params = array();

//Document will be indexed to log_index/log_type/autogenerate_id
$client->index($params);
}
echo 'create index done!';
}

}
set_time_limit(0);

?>1）创建：

$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);2）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
);

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' and product_id!=20 limit 200,10;include('./vendor/autoload.php');

$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;4）删除文档：
include('./vendor/autoload.php');
$elastic = new Elasticsearch\Client();
$index['index'] = 'test'; //索引名称
$index['type'] = 'ems_test'; //类型名称
$index['id'] = 2;
$elastic->delete($index);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['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;5）PHP 版elasticsearch 数据更新update和updateByQuery方法
根据id去更新，这时候调用的是update方法：
public static function updateEsById($id,$data = [])
{
if (empty($id) || empty($data)){
return false;
}
$es = new Elastic();
$data=[
'index' => self::$es_index,
'type' => self::$es_type,
'id' => $id,
'body' => [
'doc'=> $data //这里的data是个一维关联数组，和常用的ORM更新方法参数一致。
]
];
$res = $es->update($data);
return $res['result'];
}不知道需要更新数据的id，或者说我们需要根据条件批量更新，这时候可以用updateByQuery方法：
条件是多个，并且都是=，当然也可以根据range等逻辑运算进行过滤
/**
* Notes :
* @param array $where
* @param string $field
* @param string $value
* @return bool
* author: leojen
* @date: 18-11-21 下午6:06
*/
public static function upByWhere($where = [],$data = [])
{
if (empty($where) || empty($data)){
return false;
}
$fields = '';
foreach ($data as $k=>$v){
$fields .="ctx._source.{$k} = $v;";
}
$fields = trim($fields,';');
$params = [
'index' => self::$es_index,
'type' => self::$es_type,
'body' => [
'query' => [
'bool'=>['must'=>[]]
],
'script'=>[
"inline"=> $fields,
'lang'=>'painless'
]
]
];
foreach ($where as $key=>$val){
$params['body']['query']['bool']['must'][] = [
'term' => [
$key =>$val
]
];
}
$client = new Elastic();
return $client->updateByQuery($params);
