You need at index time to index you document as:
{
"user": "user1",
"birthday": "2001-03-04",
"birthday_month_day": "03-04"
}
This is something easily solvable on the client side (on your side) but you can also think about an ingest Script processor.
en....it's a simple way，
I originally thought that es had native support
May be it is doable but it will be super slow.
I mean that you are probably looking for best practices here.
Solving the problem at index time is always better IMO.
