#:type可设置 "web","books","news","blogs","video","local","images","patent"等
#分别对应搜网页，搜书，新闻...
#hl可选有"en","zh-cn"等..
results = client.search :q => "ruby", :hl =>'zh-cn'
pp results
results.each do |result|
   puts "+"*30
   puts ":cache url: #{result.cache_url}"
   puts ":content: #{result.content}"
   puts ":gsearch_result_class: #{result.g_search_result_class}"
   puts ":title #{result.title}"
   puts ":title no formatting: #{result.title_no_formatting}"

end

不过，在测试搜书的时候出现错误..查了下源代码，是这里的问题：

def initialize(result)
    result.each do |key, value|
      string ="#{underscore(key.to_s)}='#{value'}"
      eval "@#{string}"
    end
  end

原来搜关键词ruby搜到了《the pragmatic programmer's guide》......看来高手也犯错误..
改了一下：

def initialize(result)
    result.each do |key, value|
      string = %Q{#{underscore(key.to_s)}=%q{#{value}}}
      eval "@#{string}"
    end
  end
