ElasticSearch: How to query a date field using an hours-range filter

Question

Currently, I already know how to filter a days range from a (timestamp) date field. That\'s an easy one:

\"range\": {
    \"date\": {
        \"gte\": \"2015         


        

Answer 1

Here's what I once used to only get results from start of current day to 6pm:

{
  "query": {
    "bool": {
      "must": [
        {
          "query_string": {
            "query": "(log_message:\"My Search String\")"
          }
        },
        {
          "range": {
            "@timestamp": {
              "time_zone": "CET",
              "gt": "now-24h/d",
              "lte": "now-24h/d+18h"
            }
          }
        }
      ]
    }
  }
}

the important part is "now-24h/d" which will round to midnight / begin of current day, although it is a bit tricky as it depends on whether you use gt/lt(e), see reference doc for details.
