You can optionally specify a set of query flags.
Example
The following example obtains the first 3 Italian restaurants in the 10075 zip code, sorted alphabetically.
MongDB shell:
db.restaurants.find({ cuisine: "Italian", "address.zipcode": "10075" }).sort({ name: 1 }).limit(3)
Delphi:
MyCursor := MyCollection.Find
.Match
.Add('cuisine', 'Italian')
.Add('address.zipcode', '10075')
.&End
.Sort
.Ascending(['name'])
.&End
.Limit(3);
C++:
_di_IMongoCursor MyCursor = MyCollection->Find()
->Match()
->Add("cuisine", String("Italian"))
->Add("address.zipcode", String("10075"))
->End()
->Sort()
->Ascending(OPENARRAY((String("name"))))
->End()
->Limit(3)
->Open();
