we use ES 1.4.4
We have three fields who stores a date [format is the unix timestamp; in example 1461668482]
So far we save the field as a string - date detection is enabled.
A "from-to date aggregation // gt< date range query" works anyway - even if the fields are defined as strings.
Now we want to use an integer or date field type.
When date field type: with format "epoch_second"
A formatter for the number of seconds since the epoch. Note, that this timestamp allows a max length of 10 chars, so only dates between 1653 and 2286 are supported. You should use a different date formatter in that case.
But this date format is not defined in ES 1.4.4
When we use an integer i dont think that the date aggregations // date range querys still work.
Which field type did you use / would use for store and querys on unix timestamps in ES 1.4.4 ?
