My end goal is to implement cursor based pagination in MongoDB, while sorting on 2 properties.
Suppose we have the following collection:
+--------------------------------------+------+-------+
| _id | cost | vip |
+--------------------------------------+------+-------+
| ObjectId("5dae005e665fc34b03c70f8a") | 700 | true | <-- first query
| ObjectId("5dae005e665fc34b03c70f8c") | 50 | true | <-- first query
| ObjectId("5dae005e665fc34b03c70f88") | 1 | true | <-- second query
| ObjectId("5dae005e665fc34b03c70f8b") | 1200 | false | <-- second query
| ObjectId("5dae005e665fc34b03c70f87") | 400 | false |
| ObjectId("5dae005e665fc34b03c70f89") | 300 | false |
+--------------------------------------+------+-------+
And we want the result sorted: {vip: -1, cost: -1}, with a limit of 2. The first query would return row 1 & 2, with the end-cursor being (ObjectId("5dae005e665fc34b03c70f8c")).
With this info, how do I fetch the next 2 rows (i.e. row 3 + 4)?
I have tried with the following filter, but to no help.
{_id: {$lt: ObjectId('5dae005e665fc34b03c70f8c')}, cost: {$gt: 1}}
Thanks for your help.
