ElasticSearch 筛选需要的多个字段

Question

我有这个 ElasticSearch 6.2 查询（通过 PHP 客户端）：

[
    "query"=> [
        "bool" => [
            "filter" => [
                "term" => [ "row.name" => $name ],
                "term" => [ "row.origin" => $origin ]
            ]
        ]
    ],
    "size" => "10"
]

如果我只对 row.name 或 row.origin 使用一次搜索，它会起作用，但如果同时使用两者，它的工作方式就像 OR 和 return 的所有结果。我如何才能过滤到 return 与 row.name 和 row.origin

你的方法是正确的，但我猜你漏掉了括号。

而不是：

[
    "query"=> [
        "bool" => [
            "filter" => [
                "term" => [ "row.name" => $name ],
                "term" => [ "row.origin" => $origin ]
            ]
        ]
    ],
    "size" => "10"
]

你应该有：

[
    "query"=> [
        "bool" => [
            "filter" => [
                ["term" => [ "row.name" => $name ]],
                ["term" => [ "row.origin" => $origin ]]
            ]
        ]
    ],
    "size" => "10"
]

在您的例子中，您创建了一个具有两个相同 (term) 键的地图：

[
  "term" => [ "row.name" => $name ],
  "term" => [ "row.origin" => $origin ]
]

所以第二个 term 覆盖了第一个，实际上，你发送了：

[
  "term" => [ "row.origin" => $origin ]
]

要发送您需要的多个 term 过滤器，以便将它们视为列表：

[
  ["term" => [ "row.name" => $name ]],
  ["term" => [ "row.origin" => $origin ]]
]
