# Sử dụng AND và OR cùng nhau trong MongoDB

## Ví dụ <a href="#v-d" id="v-d"></a>

Ví dụ sau hiển thị các Document mà có các like lớn hơn 100 và có title là hoặc 'MongoDB Overview' hoặc bởi là 'tutorials point'. Mệnh đề WHERE trong truy vấn SQL tương đương là **'where likes>10 AND (by = 'tutorials point' OR title = 'MongoDB Overview')'**

```
>db.mycol.find({"likes": {$gt:10}, $or: [{"by": "tutorials point"},{"title": "MongoDB Overview"}]}).pretty()

{

"_id": ObjectId(7df78ad8902c),

"title": "MongoDB Overview",

"description": "MongoDB is no sql database",

"by": "tutorials point",

"url": "http://www.tutorialspoint.com",

"tags": ["mongodb", "database", "NoSQL"],

"likes": "100"

}
