我有解决方案，希望对您有所帮助。我花了数小时的摆弄和实验。这里是：
require "elasticsearch"require "json"search_term = "big data"city = "Tokyo"client = Elasticsearch::Client.new log: trueh = client.search index: 'swiss_candidates', body:{ query: { bool: { must: [ { match: { tags: search_term } }, { match: { city: city } } ] } }}data = JSON.parse(h.to_json) data["hits"]["hits"].each do |r|puts r["_id"]puts r["_source"]["first"]puts r["_source"]["tags"][1]puts r["_source"]["screened"][0]end重要的事情似乎是将elasticsearch结果转换为红宝石友好的东西。
