ruby - 如何使用 ruby​​ twitter gem 获取大量推文

Question

我写了一些 ruby​​ 来返回一个时间范围内所有包含一个短语的推文。但是，此代码最多会返回 1,500 条推文。我怎样才能获得超过 1,500 条推文？ (我希望获得数十万条推文)

require "rubygems"
require "twitter"

    # returns a list of tweets containing the phrase within the dates specified
    # returns either @max_tweets tweets or all tweets found
    # @param phrase - a phrase to search for
    # @param from_date - begining date of the search ex."2011-02-28"
    # @param until_date - ending date of the search ex. "2011-03-01"
    def get_tweets(phrase, from_date, until_date)

      search = Twitter::Search.new.containing(phrase).since_date(from_date).until_date(until_date)

      #get all the tweets
      tweets = search.fetch
      next_tweets = search.fetch_next_page
      while(tweets.size < @max_tweets && next_tweets != nil) 
        tweets = tweets + next_tweets
        next_tweets = search.fetch_next_page
      end

      return tweets.first(@max_tweets)
    end

Twitter API docs状态

rpp
The number of tweets to return per page, up to a max of 100.
http://search.twitter.com/search.json?rpp=100

page
The page number (starting at 1) to return, up to a max of roughly 1500 results (based on rpp * page).
http://search.twitter.com/search.json?page=10

所以看起来 1500 是一个内置限制。
