Variable AggregateOptions.hint

The index to use for the aggregation. The index is on the initial collection / view against which the aggregation is run.


							
					struct AggregateOptions
					

					
						{
						

					
					  // ...
					

					  std.typecons.Nullable!(vibe.data.bson.Bson) hint
					;
					

					  // ...
					

					}

The hint does not apply to $lookup and $graphLookup stages.

Specify the index either by the index name as a string or the index key pattern. If specified, then the query system will only consider plans using the hinted index.
