"topic_id" : [ 284, 9741 ], ... "date" : numberlong("1379116800055") } i'm trying use following query: db.collection.find({"topic_id": { $in: [ 9723, 9953, 9558, 9982, 9833, 301, ... 9356, 9990, 9497, 9724] }, "date": { $gte: 1378944001000, $lte: 1378954799000 }, "_id": { $gt: objectid('523104ddbc7b9f023700193c') }}).sort({ "_id": 1 }).limit(1000) the above query uses topic_id, date index not keep order of returned results. forcing use hint({_id:1}) makes results ordered, nscanned 1 million documents though limit(1000) specified. what missing?
