Comparing multiple timestamp fields

I've document structure like

{
username : abc
login_timestamp : 2014-04-11 11:05:00 AM
logout_timestamp : 2014-04-11 11:30:00 AM
},

{
username : def
login_timestamp : 2014-04-11 11:15:00 AM
logout_timestamp : 2014-04-11 11:45:00 AM
} ,

{
username : xyz
login_timestamp : 2014-04-11 12:10:00 PM
logout_timestamp : 2014-04-11 01:15:00 PM
}

I would like to calculate number of concurrent user sessions for a given
date. For example if login_timestamp/logout_timestamp of one user overlaps
with login_timestamp/logout_timestamp of other user then they are said to
have concurrent session and in above example, users abc and def are
having concurrent sessions. Hence output should have 2 against 2014-04-11
date.

Is it possible in es and if so then can anybody help to form a query for
this?

Thanks
Vijay

Helli Vijay ,

I cant think of any straight and efficient way to implement this.
But then you can write your own map reduce script ( Feature in 1.4.0) to
gather this information -

Thanks
