Elasticsearch groovy script to check parameter inclusion in array
This seems to occur due to mismatch in type caused by autoboxing.
The doc['field_name].values for field mapping short, integer, long types seems to be returning a collection always of type 'Long' and the argument to contains is autoboxed to Integercausing contains to fail.
You could probably explictly cast current_user_id to the type of Long:
Example:
doc['recipe_user_ids'].values.contains(new Long(current_user_id))
Or better to use the 'find' method
doc['recipe_user_ids'].values.find {it == current_user_id}
