使用带有筛选器的match_all

Question

“{”error“：{”root_case“：[{”type“：”parsing_exception“,”reason“：”[match_all]格式错误的查询，预期[END_OBJECT]但找到[FIELD_NAME]“,”line“：”line“：1,”col“：26}”,“status”：400}“,”type“：”parsing_exception“,”reason“：”[match_all]格式错误的查询，预期[END_OBJECT]但找到[FIELD_NAME]

这是我正在构建并发送给elastic客户机的搜索参数的一个示例。

[
  "type" => "events"
  "index" => "events"
  "body" => [
    "query" => [
      "match_all" => {}
      "bool" => [
        "filter" => [
          "range" => [
            "start_date.date" => [
              "gte" => "01/05/2019"
              "lte" => "05/2019"
              "format" => "dd/MM/yyyy||MM/yyyy"
            ]
          ]
        ]
      ]
    ]
    "from" => 0
    "size" => 30
  ]
]

我似乎想不出这两个怎么用。有什么指示吗？谢谢你。

Answer 1

您需要将查询封装在bool查询中，如下所示：

"query": {
    "bool" : {
        "must" : {
        "match_all": {}
        },
        "filter": {
        "range" : { /* your filter here*/ }
        }
    }
}

只需将bool和must查询包装在match_all周围，它就可以工作了。

我不知道确切的PHP语法，但应该是这样的：

[
  "type" => "events"
  "index" => "events"
  "body" => [
    "query" => [
      "bool" => [
        "must" => [ "match_all" => {}]
        "filter" => [
          "range" => [
            "start_date.date" => [
              "gte" => "01/05/2019"
              "lte" => "05/2019"
              "format" => "dd/MM/yyyy||MM/yyyy"
            ]
          ]
        ]
      ]
    ]
    "from" => 0
    "size" => 30
  ]
]
