How to split MongoDB query and skip 5 values?

MongoDBDatabaseBig Data Analytics

To skip values in MongoDB, use skip() along with limit(). For 5 values, use limit(5). Let us create a collection with documents −

> db.demo633.insertOne({"Value":10});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0be76c954c74be91e6c1")
}
> db.demo633.insertOne({"Value":20});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0bea6c954c74be91e6c2")
}
> db.demo633.insertOne({"Value":30});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0bec6c954c74be91e6c3")
}
> db.demo633.insertOne({"Value":40});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0bef6c954c74be91e6c4")
}
> db.demo633.insertOne({"Value":50});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0bf16c954c74be91e6c5")
}
> db.demo633.insertOne({"Value":60});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0bf36c954c74be91e6c6")
}
> db.demo633.insertOne({"Value":70});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0bf86c954c74be91e6c7")
}
> db.demo633.insertOne({"Value":80});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e9c0bfa6c954c74be91e6c8")
}

Display all documents from a collection with the help of find() method −

> db.demo633.find();

This will produce the following output −

{ "_id" : ObjectId("5e9c0be76c954c74be91e6c1"), "Value" : 10 }
{ "_id" : ObjectId("5e9c0bea6c954c74be91e6c2"), "Value" : 20 }
{ "_id" : ObjectId("5e9c0bec6c954c74be91e6c3"), "Value" : 30 }
{ "_id" : ObjectId("5e9c0bef6c954c74be91e6c4"), "Value" : 40 }
{ "_id" : ObjectId("5e9c0bf16c954c74be91e6c5"), "Value" : 50 }
{ "_id" : ObjectId("5e9c0bf36c954c74be91e6c6"), "Value" : 60 }
{ "_id" : ObjectId("5e9c0bf86c954c74be91e6c7"), "Value" : 70 }
{ "_id" : ObjectId("5e9c0bfa6c954c74be91e6c8"), "Value" : 80 }

Following is the query to split query and skip 5 values −

> var dividePage=2;
> db.demo633.find().skip((dividePage-1)*5).limit(5);

This will produce the following output −

{ "_id" : ObjectId("5e9c0bf36c954c74be91e6c6"), "Value" : 60 }
{ "_id" : ObjectId("5e9c0bf86c954c74be91e6c7"), "Value" : 70 }
{ "_id" : ObjectId("5e9c0bfa6c954c74be91e6c8"), "Value" : 80 }
