Cosmos DB ETag If-None-Match query support

[XzaR90]

I wonder if it is possible to use etag to query cosmos DB for matching or none matching document?

If it is not possible It would be nice to have some LINQ extensions for it, .IfMatch(string etag) and .IfNoneMatch(string etag)
I am not sure what the response should be, maybe a exception.

Cosmos doesn't support IfMatch conditions in queries, but we'll consider adding IfNoneMatch

Just a note it would be great if it does not break unit test when using inmemory database if it is going to be implemented.
