terms 查询

terms 查询与 term 查询一样，但它允许你指定多值进行匹配，如果这个字段包含了指定值中的任何一个值，那么这个文档满足条件。

# 新增文档
PUT /ad/_doc/5
{
    "name":"Vivo",
    "price":2999,
    "color":"blue",
    "ad":"this is a blue phone",
    "label":[
        "blue",
        "Vivo"
    ]
}

# 查询ad字段包含red或者blue值的文档
GET /ad/_search
{
    "query":{
        "terms":{
            "ad":[
                "red",
                "blue"
            ]
        }
    }
}
