Elasticsearch全文搜索引擎-PHP使用教程。
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。)

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(已测试过):
