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": "2015-11-01",
        "lte": "2015-11-30"
    }
}

But how to filter dates when you are interested in ranges based on hours like gte:"8:00:00" and lte:"10:00:00"? Is this possible?

My requirement in other words: How to get all the events happening this month (15-11-01/15-11-30) but only between 8:00:00 am and 10:00:00?

Answer 1

You can do it with your range filter to filter the correct days and then with a script filter to filter the desired hours, like this:

{
  "query": {
    "filtered": {
      "filter": {
        "bool": {
          "must": [
            {
              "range": {
                "date": {
                  "gte": "2015-11-01",
                  "lte": "2015-11-30"
                }
              }
            },
            {
              "script": {
                "script": {
                  "source": "doc.date.date.getHourOfDay() >= params.min && doc.date.date.getHourOfDay() <= params.max",
                  "params": {
                    "min": 8,
                    "max": 10
                  }
                }
              }
            }
          ]
        }
      }
    }
  }
}

Note that you need to make sure to enable dynamic scripting in order for this query to work.

If I understood your question correctly then I think you have to add new field which indexes only time like

PUT your_index
{
  "mappings": {
    "your_type": {
      "properties": {
        "time": {
          "type":   "date",
          "format": "HH:mm:ss"
        }
      }
    }
  }
}

Then you can query like this

{
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "date": {
              "gte": "2015-11-01",
              "lte": "2015-11-30"
            }
          }
        },
        {
          "range": {
            "time": {
              "gte": "08:00:00",
              "lte": "10:00:00"
            }
          }
        }
      ]
    }
  }
}

Does this help?
