Work on this items has not progressed. After reviewing this we need to revert this back to under-review.
This work is planned but is more long-term road map.
Thank you for your patience.
Hello Daniel.
Yes, on our Control Plane we are adding a number of improvements that should be coming out over the next few months which should provide this level of control.
Thanks!

More details on Azure Cosmos DB on Azure Stack will follow as we make progress on it.
Thanks for the feedback.
We are still reviewing this as there are a number of dependencies and teams involved. We will update the status here as this progresses.
Thanks.

Reopening this user voice item as our support for Skip/Take (Offset/Limit) was only limited to single partition queries.
Update.
The newly released .NET SDK v3 now includes support for x-partition queries using Offset/Limit. You can learn more about v3 SDK and try it and provide feedback on our github repo here.
github.com/azure/azure-cosmos-dotnet-v3We will also be back-porting this functionality to our .NET v2 SDK. This work will begin shortly and we anticipate it to be released in September.
Once that is released we will mark this feature as complete.
Thank you for your patience and votes.
We can't give an exact date but this is actively being worked on now and expect soon.
Thanks!
At this time, I can say we are working on some foundational pieces which will light up skip/take in future.

For this we recommend using Azure Search. This is not on our roadmap. If that ever changes we will reopen this item.
Thanks.
Pretty much all of $text functionality (and more) has been implemented in Azure Search and we're happy to let you know that it now supports for MongoDB API collections (in private preview). Working with MongoDB collections is very similar to working with SQL Cosmos DB collections as described in https://docs.microsoft.com/azure/search/search-howto-index-cosmosdb
To create a MongoDB datasource, POST an HTTP request as shown below:
POST https://[service name].search.windows.net/datasources?api-version=2016-09-01
Content-Type: application/json
api-key: [Search service admin key]
{
"name": "mymongodbdatasource",
"type": "documentdb",
"credentials": {
"connectionString": "AccountEndpoint=https://<Your Cosmos DB account name>.documents.azure.com;AccountKey=<Your Cosmos DB account key>;Database=<Your database>;ApiKind=MongoDb"
},
"container": { "name": "<Your collection>", "query": null },
"dataChangeDetectionPolicy": {
"@odata.type": "#Microsoft.Azure.Search.HighWaterMarkChangeDetectionPolicy",
"highWaterMarkColumnName": "_ts"
}
}Note:
1. Use `documentdb` as the data source type.
2. Do not use a MongoDB connection string that you would use in your MongoDB application. Instead, construct the connection string as shown above. Make sure to add **ApiKind=MongoDb** to the connection string.Once you've created the data source, follow the steps in https://docs.microsoft.com/azure/search/search-howto-index-cosmosdb to create a search index, create an indexer, and monitor the indexer execution.
## Known issues and limitations
1. Only the REST API is supported. For now, you cannot create or edit MongdoDB data sources using Azure Portal or Azure Search .NET SDK. However, you **can** monitor execution history of MongoDB indexers in the portal.
2. Custom queries are not supported: `container.query` parameter must be set to null or omitted. If you need to use a custom query, please let us know at the emails below.
If you encounter any issues, please contact azscustquestions@microsoft.com
Currently, simple text search is provided through $regex operator. More comprehensive text search is coming shortly through Azure Search that will be able to index MongoDB API collections as well: https://feedback.azure.com/forums/263029-azure-search/suggestions/18861421-documentdb-indexer-should-be-able-to-index-mongodb

We are currently working on this feature and have made it available in Preview in the Azure Portal.
Please feel free to test Aggregation Pipeline support for your MongoDB API accounts in Cosmos DB by opening your MongoDB API account, then clicking on “Preview” tab on left hand side and then Enable for Aggregation Pipeline.
While there please feel free to test support for MongoDB 3.4 support as well as Per-Document TTL support.
Thank you for your request and votes.
We are implementing a number of changes in aggregation pipeline this quarter. Some of the results will bee seen in both speed and RU charges by the end of April 2018.
replaceRoot support is on our roadmap. The workaround currently is to use simple $project: { _id:0, "<document_root>":1 } stage instead. It will give pretty much same results, except that it will include the name of the field used as a new document_root as well, which you can filter out (or simply omit) on the client side.

This work is currently under way. Will update here as this moves towards general availability.
Thank you for your suggestion and votes.
Currently, projection definition only supports "1" to include the field in projection (as per https://docs.mongodb.com/manual/tutorial/project-fields-from-query-results/#return-the-specified-fields-and-the-id-field-only)
As a workaround, can you try the following command
Command: db.getCollection('Employee').find({ "FullName": /User/i}).projection({ "FullName" : 1 })
This falls under the Azure Storage Team. Changing category.
