Mongodb find query return only unique values no duplicates

Question

I have a collection of documents           networkID    myNetwork1        pointID    point001        param    param1           networkID    myNetwork2        pointID    point002        param    param2           networkID    myNetwork1        pointID    point003        param    param3          pointIDs are unique but networkIDs are not   Is it possible to query Mongodb in such a way that the result will be    myNetwork1 myNetwork2   right now I only managed to return  myNetwork1 myNetwork2 myNetwork1   I need a list of unique networkIDs to populate an autocomplete select2 component  As I may have up to 50K documents I would prefer mongoDb to filter the results at the query level

I think you can use db collection distinct fields query    You will be able to get the distinct values in your case for NetworkID    It should be something like this     Db collection distinct  NetworkID

[mongodb] Mongodb find() query : return only unique values (no duplicates)
