mongodb - Designing a database for querying by dates? -


for example, need query last 6 months earliest instance each day (and last day earliest instances in each hours, , last day minutes). thinking of using mongodb , having nested structure like

year:{ month:{ day: { hour: { minute: [array of seconds]

but first instance have sort array costly. there easier way?

would better have date field.

and query like:

find(date: {$gt : 'starting_date', $lt : 'ending_date'})
