Function_score, gaussian decay, handling multiple by zero

Elastic Stack Elasticsearch
2

function_score allows you to combine functions in any arbitrary way. For example, to avoid 0 scores, you can add an arbitrary value 0.001 to your gaussian values by using weight of 0.001 and score_mode of sum:

"function_score" : {
		"functions": [
			{
				"gauss": {
					"geo.coordinates": {
						"origin": { "lat": 14.18, "lon": -169.67 },
						"scale": "2km"
					}
				}
			},
			{
				"weight" : 0.001
			}
		],
		"score_mode" : "sum"
	}

Will this solve your problem?
