ruby-on-rails - ElasticSearch + Rails多个 `must`无法正常工作

Question

根据文档，我正在使用以下语法:

self.search(
  query: {
    bool: {
      must: { match: { type: 'user' } },
      must: { match: { status: status } },
      must: { range: { created_at: { from: date_from, to: date_to } } }
    }
  },
  size: 1000
)

我相信它应该在寻找所有3个条件，但是查询会忽略所有 must，但最后一个:
<Elasticsearch::Model::Searching::SearchRequest:0x000000039b2c08
@definition=
{:index=>"uusers",
:type=>"user",
:body=>{:query=>{:bool=>{:must=>{:range=>{:created_at=>{:from=>Mon, 25 Aug 2014, :to=>Thu, 18 May 2017}}}}}, :size=>1000}}
我究竟做错了什么？

Answer 1

当有多个语句时，必须将其添加到数组中，如下所示:

self.search(
  query: {
    bool: {
      must: [
        { match: { type: 'user' } },
        { match: { status: status } },
        { range: { created_at: { from: date_from, to: date_to } } }
      ]
    }
  },
  size: 1000
)
