I am trying to use function_score in a Kibana 4 search. The query I am issuing is:
{"function_score":{"field_value_factor":{"field":"purchases","modifier":"log1p"}}}
I tried to write it in the query bar and also in the advanced query editor (Edit Saved Objects).
I get the following error:
The mapping of the field "purchases" is:
"purchases": { "type" : "long" }
What am I doing wrong?
