You can use function_score to boost your doc base on a custom formula.Refer here (script_score section) for more details:https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html

You can also use decay functions to boost recently created documents over older results, refer here for sample:https://www.elastic.co/blog/0-90-4-released/
