# \$1skip
<a name="skip"></a>

在 Amazon DocumentDB 中，`$skip`运算符用于偏移查询结果的起点，允许您检索匹配文档的特定子集。这在分页场景中特别有用，在这种场景中，您要检索结果的后续页面。

**参数**
+ `skip`：返回剩余文档之前要跳过的文档数。

## 示例（MongoDB 外壳）
<a name="skip-examples"></a>

以下示例演示如何使用`$skip`运算符从集合中检索第二页结果（文档 11-20）。

**创建示例文档**

```
db.collection.insert([
  { "name": "Document 1" },
  { "name": "Document 2" },
  { "name": "Document 3" },
  { "name": "Document 4" },
  { "name": "Document 5" },
  { "name": "Document 6" },
  { "name": "Document 7" },
  { "name": "Document 8" },
  { "name": "Document 9" },
  { "name": "Document 10" },
  { "name": "Document 11" },
  { "name": "Document 12" },
  { "name": "Document 13" },
  { "name": "Document 14" },
  { "name": "Document 15" },
  { "name": "Document 16" },
  { "name": "Document 17" },
  { "name": "Document 18" },
  { "name": "Document 19" },
  { "name": "Document 20" }
]);
```

**查询示例**

```
db.collection.find({}, { "name": 1 })
             .skip(10)
             .limit(10);
```

**输出**

```
[
  { "_id" : ObjectId("..."), "name" : "Document 11" },
  { "_id" : ObjectId("..."), "name" : "Document 12" },
  { "_id" : ObjectId("..."), "name" : "Document 13" },
  { "_id" : ObjectId("..."), "name" : "Document 14" },
  { "_id" : ObjectId("..."), "name" : "Document 15" },
  { "_id" : ObjectId("..."), "name" : "Document 16" },
  { "_id" : ObjectId("..."), "name" : "Document 17" },
  { "_id" : ObjectId("..."), "name" : "Document 18" },
  { "_id" : ObjectId("..."), "name" : "Document 19" },
  { "_id" : ObjectId("..."), "name" : "Document 20" }
]
```

## 代码示例
<a name="skip-code"></a>

#### [ Node.js ]

```
const { MongoClient } = require('mongodb');

async function main() {
  const client = await MongoClient.connect('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false');
  const db = client.db('test');
  const collection = db.collection('collection');

  const results = await collection.find({}, { projection: { name: 1 } })
                                 .skip(10)
                                 .limit(10)
                                 .toArray();

  console.log(results);

  await client.close();
}

main();
```

#### [ Python ]

```
from pymongo import MongoClient

def main():
    client = MongoClient('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false')
    db = client.mydatabase
    collection = db.collection

    results = list(collection.find({}, {'name': 1})
                   .skip(10)
                   .limit(10))

    print(results)

    client.close()

if __name__ == '__main__':
    main()
