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: true
h = 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。
