我现在能想到的唯一的办法就是在串查询使用_missing_
和_exists_
:
require 'tire'
require 'active_support/core_ext/numeric/time'
require 'active_support/core_ext/date/calculations'
require 'active_support/duration'
Time::DATE_FORMATS.update :lucene => "%Y-%m-%dT%H:%M:%S%z"
Tire.index('events_stackoverflow_demo').delete
class Event
include Tire::Model::Persistence
property :title
property :starts_at, type: 'date'
property :ends_at, type: 'date'
index_name 'events_stackoverflow_demo'
end
Event.create id: 1, title: 'Test 1', starts_at: 2.days.ago, ends_at: 1.days.ago
Event.create id: 2, title: 'Test 2', starts_at: 1.day.ago, ends_at: 1.day.since
Event.create id: 3, title: 'Test 3', starts_at: 1.day.since
Event.tire.index.refresh
upcoming = Event.search do
query do
boolean minimum_number_should_match: 1 do
should { string "_exists_:ends_at AND ends_at:[#{Time.now.to_s(:lucene)} TO *]" }
should { string "_missing_:ends_at AND starts_at:[#{Time.now.to_s(:lucene)} TO *]" }
end
end
p to_curl
end.results
puts "---"
p upcoming
大,抽出时间来回答谢谢:)我会尽力今晚。 – Robin 2012-03-19 22:13:55
会有更好的方法来定义'starts_at:[#{Time.now.to_s(:lucene)} TO#{100.days.since.to_s(:lucene)}]'?这是否被转换为范围查询?我可以使用'FROM'吗?因为100天是任意的。 – Robin 2012-03-19 22:18:50
我意识到这只是lucene语法,根据以下链接,它似乎不可能:(http://lucene.apache.org/core/old_versioned_docs/versions/3_0_0/queryparsersyntax.html#Range搜索 – Robin 2012-03-19 23:43:49
