Range query not working with format

[Steven_Ensslen]

Hi all, I think that I've come across a defect.

I have an index with a date field, start_datetime

This more restrictive query returns data
GET /_search
{
"query": {
"range" : {
"start_datetime" : {
"gte": "10-05-2018",
"lte": "12-05-2018",
"format": "dd-mm-yyyy"
}
}
}
}

While this query, which asks for a superset of the previous query, returns nothing:
GET /_search
{
"query": {
"range" : {
"start_datetime" : {
"gte": "10",
"lte": "12",
"format": "dd"
}
}
}
}

I get a respoonse for May 10 to 12 of this year, but no data for the 10th to 12th of all months in all year.

Is this behaviour documented or should I open an issue?

The format, needs to expand to a specific date in order to be able to execute a range query.

if you need to filter by specific days of the month, the best strategy would be to extract that day into it's own field day_of_month, which as a short, and then do a simple range query against that.

Thanks Alex,

I've opened issue 30634 for the documentation. Please comment on that issue with (a link to?) the information that should be in the documentation.
