Distinct

The Limit method operates on the IFindFluent interface. It limits the number of documents to query from the database.

warning

Results must not be larger than the maximum BSON size (16 MB). If your results exceed the maximum BSON size, use the aggregation pipeline to retrieve distinct values using the $group operator, as described in Retrieve Distinct Values with the Aggregation Pipeline.
