Opensearch的yii2扩展

===============================

阿里云的Opensearch的yii2扩展

## 使用方式

#### 1 Raw方式

就是直接调用OpenSearch类的search/suggest方法 和opensearch通信返回结果

#### 2 ActiveRecord类实现

仿照yii2的db ActiveRecord的设计和调用方式

代码放在db里面 使用的时候继承和配置SearchModel

SeachModel

===============================

- 1 index --> 定义表名

- 2 mapping --> 定义字段的类型 int / string / int_array / string_array

- 3 search / suggest -->  search/suggest 对应的instance名字 (默认就叫search/suggest)

SearchQuery

===============================

```

基本调用

$modelArr = SearchModel::search()->filter()->andFilter()->orderBy()->limit()->offset()->all();

SearchModel::search() / suggest()

->select([]) // fields

->query() // query

->filter(['type' => new SearchInt(1)]) // filter //'type'=>'1' 'type'=>1 bigint '1234'

->andFilter(['status' => 10]) // andWhere

->orFilter(['like', 'catgy', 'bc']) // orWhere

// andFilter and tag in ('8','9','10') // int string

->andWhere(['in', 'tag', [8,9,10]])

->all();

```

filter的特殊之处

===============================

```

本质原因是 search和sql还是有些不同的

    int型的是通用的

    string类型search有3中: text/shortText/literal

        text: 用于通用的搜索分词

        shortText: 用于实现类似like的搜索

        literal：也就是exactly match 精准匹配

    array类型:

        literal_array: 用or操作来实现了 in/not in

        int和其他类型的array: opensearch有原生的in/not in支持

```
