ElasticSearch - How can I reuse script_fields field in aggregation?
It is possible to use a script_field to compute a field, 'emp_salary', and use in an aggregation query? Here's an example.
I have a script_fields script to compute the 'emp_salary', and I want to use it in the aggregation sub query but I get
"query":
"term":
"name.keyword": "John"
,
"script_fields":
"emp_salary":
"script":
"lang": "painless",
"source": """return 1"""
,
"aggs":
"average":
"avg":
"field": "_field['emp_salary']"
but I get null for the 'emp_salary'. Am I accessing the field value wrong?
"aggregations":
"average":
"value": null
Thanks
