database - 弹性5.5

我正在尝试使用 flex 5.5建立强制的搜索(使用 flex 2。*我找到了有关如何执行此操作的信息，但是在5.5中我无法找到)

如果用户将选择使用某些属性进行筛选，那么我想显示金额提示的东西并不稀奇，类似于商店。 Image for visualisation

数据集示例:

[
  {
    "id" : "978-0641723445",
    "cat" : ["book","hardcover"],
    "name" : "The Lightning Thief",
    "author" : "Rick Riordan",
    "series_t" : "Percy Jackson and the Olympians",
    "sequence_i" : 1,
    "genre_s" : "fantasy",
    "inStock" : true,
    "price" : 12.50,
    "pages_i" : 384
  }
,
  {
    "id" : "978-1423103349",
    "cat" : ["book","paperback"],
    "name" : "The Sea of Monsters",
    "author" : "Rick Riordan",
    "series_t" : "Percy Jackson and the Olympians",
    "sequence_i" : 2,
    "genre_s" : "fantasy",
    "inStock" : true,
    "price" : 6.49,
    "pages_i" : 304
  }
,
  {
    "id" : "978-1857995879",
    "cat" : ["book","paperback"],
    "name" : "Sophie's World : The Greek Philosophers",
    "author" : "Jostein Gaarder",
    "sequence_i" : 1,
    "genre_s" : "fantasy",
    "inStock" : true,
    "price" : 3.07,
    "pages_i" : 64
  }
,
  {
    "id" : "978-1933988177",
    "cat" : ["book","paperback"],
    "name" : "Lucene in Action, Second Edition",
    "author" : "Michael McCandless",
    "sequence_i" : 1,
    "genre_s" : "IT",
    "inStock" : true,
    "price" : 30.50,
    "pages_i" : 475
  }
]

谢谢!

最佳答案

您只需要使用aggs即可代替多方面的功能。聚合比方面要强大得多。

例如:

GET index/_search
{
    "aggs" : {
        "countries" : {
            "terms" : { "field" : "country" }
        },
        "types" : {
            "terms" : { "field" : "type" }
        }
    }
}

然后，如果用户单击“构面”，则只需在bool查询中添加filter子句(这将更新所有构面计数)，或者添加post_filter仅筛选结果(不影响聚合)。
