Question

我无法从elasticsearch服务器获得匹配。我的代码-

client = Elasticsearch::Client.new log: true
client.indices.refresh index: 'property_index'
# search_results = client.search(body: { query: { multi_match: { query: search_params, fields: ['street_address', 'suburb'] } } })
match_query = [
  { match: { status: 'Active'} }
]
match_query << { match: { is_published: true} }
match_query << { match: { paid: true} }
match_query << { match: { suburb: params[:suburb].to_s} } if !params[:suburb].blank?
match_query << { match: { advertise_type: params[:advertise_type].to_s} } if !params[:advertise_type].blank?
match_query << { match: { state: params[:state].to_s} } if !params[:state].blank?
match_query << { match: { postal_code: params[:postal_code]} } if !params[:postal_code].blank?
response = client.search(body: {
                                  query: { bool: { must: match_query }},
                                  sort: [
                                    { updated_at: { order: "desc" }}
                                  ]
                              }, from: params[:offset], size: params[:limit])

all_records = client.search(body: {
                query: { bool: { must: match_query }},
                sort: [
                  { updated_at: { order: "desc" }}
                ]
              })

这是我得到的响应输出-

Answer 1

如果我们不了解查询的结构或您要通过查询实现的目标，很难说出问题所在。

信息日志显示以下内容：

timed_out:false
Shards:
 total:1 
 successful: 1
 failed:0
Hits: 
 total: 0

这意味着查询成功，并且服务器未遇到任何错误。它只是找不到与您的查询匹配的文档。

我建议您使用适当的工具首先尝试您的查询，例如Kibanas的搜索分析器（https://www.elastic.co/guide/en/kibana/current/xpack-profiler.html）。

这将向您显示有关查询的信息，一旦找到合适的查询，便可以将其集成到代码中。
