Basic query:
q = GScraper::Search.query(:query => 'ruby')
Advanced query:
q = GScraper::Search.query(:query => 'ruby') do |q|
q.without_words = 'is'
q.within_past_day = true
q.numeric_range = 2..10
end
Queries from URLs:
q = GScraper::Search.query_from_url('http://www.google.com/search?as_q=ruby&as_epq=&as_oq=rails&as_ft=i&as_qdr=all&as_occt=body&as_rights=%28cc_publicdomain%7Ccc_attribute%7Ccc_sharealike%7Ccc_noncommercial%29.-%28cc_nonderived%29')
q.query # => "ruby"
q.with_words # => "rails"
q.occurs_within # => :title
q.rights # => :cc_by_nc

q.first_page.select do |result|
result.title =~ /Blog/
end
q.page(2).map do |result|
result.title.reverse
end
q.result_at(25) # => Result
q.top_result # => Result
A Result object contains the rank, title, summary, cahced URL, similiar query URL and link URL of the search result.
