Sort by groovy _script

Elastic Stack Elasticsearch
1

Hey there!

I'd like to sort my results by groovy script but i have problem selecting
the right field values from a multi valued field.

I try to select only the value at index 2 (or 10343) from a multivalued
field.

"script": "abs((doc['multi_field'].values[0] - param1)+(doc['multi_field'].values[1]

  • param2))",

How can i select the value at a specific index. Is there a way to do it
with a multivalued field or must i index the fields seperatly?

Thanks for helping

Ps:

This part

"script": "abs((doc['multi_field'].values[0] - param1)+(doc['multi_field'].values[1]

  • param2))",

throws following exception

Query Failed [Failed to execute main query]]; nested:
GroovyScriptExecutionException[NullPointerException[Cannot invoke method
minus() on null object]]; }]",
