Hello!
Is it possible to create range (from-to) query? I found only the way how to get all values starting from the specific value until the first (last) one.

Hi,

Yes it is quite straightforward. You need to iterate and compare each key, until 'to' is matched.
Do you need this for optimization reasons?

Hi.
It is just a feature. I can check keys as you mentioned in my client code (golang). 
But if there would be a possibility to implement range queries on multiple keys it would be very nice. 
And "IN" queries (presently  within cursor loop I check key entry in an array and skip "record" failed check)
