Document aggregation

It looks like the aggregate method isn't documented in readme.md. Not sure if this was intentional or not.

@chaitu14341 Yes I am using aggregate extensively. The docs are in the source code here https://github.com/mixmaxhq/mongo-cursor-pagination/blob/master/src/aggregate.js#L5

No, with mongoose plugin there is only find method. I'm trying to add aggregate() into mongoose plugin but still not working as expected.

Update: Actually it works, I've just confused because the aggregate() method of this plugin add the $sort based on _id right after the aggregated results, which make my $geoNear results completely shuffled. Otherwise it works.

@sangdth, I am not seeing aggregate.js being required or used in the mongoose.plugin.js. How were you able to use aggregate rather than find() or search()?

Hi @nathanielrindlaub, unfortunately I forgot the context, it's 2020 my friend. But a quick look into the source code, I think you can't use aggregate() if you want to use it as Mongoose's plugin. Mongo and Mongoose are different things.

They export separated things in the index.js file, so I believe the last time I had to give up on using this code.
