Filtering on a mapped timestamp

I have been moving from an auto-generated timestamp to a mapped one and query doesn’t work anymore. When using an auto-generated timestamp, I was able to perform this sort of query:

FilterBuilder filter = FilterBuilders.rangeFilter("_timestamp").from(zonedDateTime.toLocalDate().toString()).to(zonedDateTime.plusHours(1).toLocalDate().toString());

but also passing date expressions such as “now-1h” would work. Now that I have introduced the following mapping:

"collections": {
  "_timestamp": {
    "enabled": true,
    "path": "my_date",
    "ignore_missing": false
  "properties": {
    "author": {
      "type": "string",
      "index": "not_analyzed"
    "name": {
      "type": "string",
      "analyzer": "lowercase"
    "my_date": {
      "type": "date"

And I store my_date as a Unix EPOCH format, I can’t query anymore:


Return empty results, while the query


Fails with an exception

from[-1],size[-1]: Parse Failure [Failed to parse source [{"query":{"filtered":{"query":{"match_all":{}},"filter":{"range":{"my_date":{"from":"2015-09-04T19:52:15.001+01:00","to":"2015-09-04T21:52:15.001+01:00","include_lower":true,"include_upper":true}}}}}}]]]; nested: NumberFormatException[For input string: "2015-09-04T19:52:15.001+01:00"];

It looks like the only query that I can do is by using the numeric values of the timestamp, on my_date. Is there anything better I can hope for?

Already answered on SO. Invalid mapping. my_date is supposed to be in the properties section.

Thanks, I have updated my question as in SO. The mappings in the posts were wrong because I copy/paste only a part of it, in reality they are correct (or I would not even be able to set them on the index)
