elasticsearch - ElasticSearch 过滤多个必填字段

Question

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

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

row.name如果我只对or使用一次搜索，row.origin它就可以工作，但两者都像 OR 一样工作并返回所有结果。如何过滤以仅返回与row.nameAND完全匹配的文档row.origin

Answer 1

你采取了正确的方式，但我猜你错过了括号。

代替：

[
    "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"
]

在您的情况下，您创建了一个带有两个相同 ( 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term您需要的多个过滤器，以便将它们视为列表：

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