在搜索查詢中提升某些關鍵字

Question

我正在嘗試在我的 mutlimatch 查詢中增加某些關鍵字，這些關鍵字比其他詞數據集 ['black kurta','blue kurta','green kurta','black pant'] 更重要，例如（搜索“black kurta”）首先應該是黑色庫爾塔，然后是“藍色庫爾塔”、“綠色庫爾塔”，最后是庫爾塔

{
    "query": {
        "multi_match" : {
      "query":      "Black kurta",
      "type":       "best_fields",
      "fields":     [ "name^3","meta_title^3","meta_description","short_description","meta_keyword^3","description^1" ],
      "tie_breaker": 0.3
    }
    }
}

試試這個，注意boost部分。

"query": {
        "bool": {
          "should": [
            {
              "multi_match": {
                "query": "black kurta",
                "fields": [
                  "name",
                  "meta_title",
                  "meta_description",
                  "short_description", ...
                ],
                "type": "phrase",
                "boost": 10
              }
            },
            {
              "multi_match": {
                "query": "blue kurta",
                "fields": [
                  "name",
                  "meta_title",
                  "meta_description",
                  "short_description",
                  ...
                ],
                "operator": "and",
                "boost": 4
              }
            },
            {
              "multi_match": {
                "query": "green kurta",
                "fields": [
                  "name",
                  "meta_title",
                  "meta_description",
                  "short_description",
                  ...
                ],
                "operator": "and",
                "boost": 2
              }
            }
          ]
        }
      }
