The offset operator in MongoDB is used in pagination where you are essentially skipping a number of documents. In MongoDB, we use the `skip()` function to offset the documents.
Here is an example:
```
db.collection.find(query).skip(offset_number)
```
In this example, `collection` is the name of the collection where you want to find documents. The `query` parameter is the filter that you pass to find a specific document and `offset_number` is the number of documents that you want to skip.
Let’s imagine we have a “users” collection and we want to skip the first 5 users in the collection. Here is how we can do it:
```
db.users.find().skip(5)
```
Remember, the offset operation can be quite expensive on large collection since it needs to traverse all the documents to get to the offset position.
Also, you can chain the skip method with the limit method to paginate through your MongoDB collection.
```
db.users.find().skip(5).limit(5)
```
This will skip the first 5 documents and then limit the result to the next 5 documents.
