sorry for my newbie question, i dont know how elasticsearch score result 😄 i read in [https://www.elastic.co/guide/en/elasticsearch/guide/current/scoring-theory.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/scoring-theory.html) it have : ``` tf(t in d) = √frequency idf(t) = 1 + log ( numDocs / (docFreq + 1)) norm(d) = 1 / √numTerms ``` In java, i try search and setExplain(True). My respone is.... ``` { "took" : 3, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 61, "max_score" : 2.8814154, "hits" : [ { "_shard" : 1, "_node" : "aJhrjUCeQsWLNYjFTHmufw", "_index" : "products", "_type" : "product", "_id" : "288", "_score" : 2.8814154, "_source":{"products_id":288,"products_code":"61-65SP287","categories_id":61,"manufacturers_id":65,"users_id":1,"users_fullname":"hong luu","products_title":"Modem Dlink DSL-526E","products_alias":"Modem-Dlink-DSL-526E","products_description":" \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n
