db.Trade.find({
'startDate': {$lte: ISODate("2017-09-08T00:00:00.000Z")},
$or: [
{
'endDate': {$gte: ISODate("2017-09-08T00:00:00.000Z")}
},
{
'endDate': {$exists: false}
}
]
}).sort({'date': -1}).limit(100).explain('executionStats')

As the executionStats description, the query will use the data_1 index.
In executionStats, it run 3s, but actually, it run 80s
