Range facet with dates computing?

Elastic Stack Elasticsearch
1

Hi All,

I like to create a facet list like:

  • this week
  • last month
  • last quarter
  • last year
  • older

I have a dataset with an adddate field. The adddate in milliseconds minus
the current date/time in millisecons gives me an amount of milliseconds
which I could use to create the facet. Within the range facet the amount of
milliseconds for the several, before, mentioned cases are definied:

"facets" : {
"test" : {
"range" : {
"key_script" : "doc['adddate'].date.getMillis - System.currentTimeInMillis",
"value_script" : "1",
"ranges" : [
{ "from" : "0", "to" : "604800000" },
{ "from" : "604800001", "to" : "2678400000" },
{ "from" : "2678400001", "to" : "2678400000" },
{ "from" : "2678400001", "to" : "7776000000" },
{ "from" : "7776000001", "to" : "31536000000" },
{ "from" : "31536000001" }
]
}
}
}

However..... it fails with the script:

PropertyAccessException[[Error: could not access: getMillis; in class:
org.elasticsearch.common.joda.time.MutableDateTime] [Near : {...
doc['adddate'].date.getMillis ....}]

Are not all methods and properties of the Joda MutableDateTime exposed and
if not..... is there another solution to get the above result. Is I only
try the System.currentTimeInMillis, it fails as well.

Thanks in advance

BTW I'm using ES 0.90.0 Beta

This should work:

"facets" : {
"test" : {
"range" : {
"key_script" : "System.currentTimeMillis() -
doc["adddate"].value",
"value_script" : "1",
"ranges" : [
{ "from" : 0, "to" : 604800000 },
{ "from" : 604800001, "to" : 2678400000 },
{ "from" : 2678400001, "to" : 7776000000 },
{ "from" : 7776000001, "to" : 31536000000 },
{ "from" : 31536000001 }
]
}
}
}

but you will might get faster performance if you will recalculate the
ranges and use adddate as a key field instead of using key_script.
