Elasticsearch查询以检查日期范围不在日期数组中

Question

I have a 'reservations' field which stores an array of dates that an item has been reserved for.

Sample data:

{
   reservations: [ "05/03/2015",
                   "05/04/2015",
                   "05/05/2015",
                   "05/18/2015",
                   "05/19/2015"
                  ]
}

I'd like to search for a date range in elastic search and return all items that do not contain dates falling on these dates.

So I have a startDate and endDate parameter to search for. However, the date range filter for elasticsearch will not fit this requirement. Can I do this in some other way?

EDIT:

I think the Date Range filter wont work because you can only compare the startDate and endDate with gte or lt to just ONE value on the right. I basically have a bunch of dates on the left (start/end date range) that I need to check against and bunch of dates on the right (the multiple reservation dates).

Answer 1

This problem can be solved by using nested object. Convert reservations as a nested object to the main document and than range queries will work.

Example

{
  reservation : [
    {"thedate" : "2015-01-01"}, 
    {"thedate" : "2015-03-12"},
    ...
  ]
}
