【问题描述】：

我在 mysql 中有一个条件查询，我想在 elasticsearch 查询中转换它：

查询：

我有带有价格范围搜索的产品列表页面。如果用户使用该搜索，我想检查产品是否有销售，那么它应该考虑销售价格或者销售价格。（检查销售：我正在检查销售开始和销售结束日期之间的当前日期。）

MySql 查询：

SELECT *
FROM `product_sku`
WHERE 
((sale_start < '2016-05-12 15:23:53' AND sale_end > '2016-05-12 15:23:53' AND sale_price between 600 AND 1800)
 OR (sale_end < '2016-05-12 15:23:53' AND selling_price between 600 AND 1800) 
)

Elasticsearch 查询：

$params = [
            'index' => 'index',
            'type' => 'product-list',
            'body' => [
                "query" => [
                    "filtered" => [
                        "query" => [
                            "match_all" => [],
                        ],
                        'query' => $query,

                        "filter" => [
                            "nested" => [
                                "path" => "default_product_low_price_with_seller",

【问题讨论】：

你的mysql查询在哪里？
我已经更新了我的问题......

标签： php laravel elasticsearch

【解决方案1】：

试试这个查询：

{
  "query": {
    "nested": {
      "path": "default_product_low_price_with_seller",
      "query": {
        "bool": {
          "should": [
            {
              "bool": {
                "must": [
                  {
                    "range": {
                      "default_product_low_price_with_seller.sale_price": {
                        "gte": 100,
                        "lte": 300
                      }
                    }
                  },
                  {
                    "range": {
                      "default_product_low_price_with_seller.sale_start": {
                        "lte": "2016-05-05"
                      }
                    }
                  },
                  {
                    "range": {
                      "default_product_low_price_with_seller.sale_end": {
                        "gte": "2016-05-05"
                      }
                    }
                  }
                ]
              }
            },
            {
              "bool": {
                "must": [
                  {
                    "range": {
                      "default_product_low_price_with_seller.selling_price": {
                        "gte": 100,
                        "lte": 300
                      }
                    }
                  },
                  {
                    "range": {
                      "default_product_low_price_with_seller.sale_end": {
                        "lte": "2017-05-05"
                      }
                    }
                  }
                ]
              }
            }
          ]
        }
      }
    }
  }
}

因此，这两个条件是全局 should 列表的分支，每个分支下都有一系列 must 语句，位于新的 bool 查询下。
