Classes

- Google::Search::Local           | local search.
- Google::Search::News            | news search.
- Google::Search::Patent          | patent search.
- Google::Search::Video           | video search.
- Google::Search::Response        | single request response, containing items. Is Enumerable
- Google::Search::Item            | single item, superclass of all other items.
- Google::Search::Item::Web       | single item containing web specific data.
- Google::Search::Item::Blog      | single item containing blog specific data.
- Google::Search::Item::Book      | single item containing book specific data.

Arbitrary Query String Support

Arbitrary key / value pairs may be passed to Google::Search.new, all options passed that are not assigned (deleted) will pass on to be part of the query string.

For argument reference visit: code.google.com/apis/ajaxsearch/documentation/reference.html#_fonje_web

Items

Each item type (web, image, etc) is a subclass of Google::Search::Item, whose constant is Google::Search::Item::{Web, Image, Blog, etc}. Every aspect of google-search is well documented, so poke around to learn more or view spec/item_spec.rb for item attributes.

Image example

Below we simply create a new :image search, and pass a :query string. Query strings are urlencoded when Search#get_uri is called, so there is no reason to do so manually.

File.open('path/to/images.html', 'w+') do |file|
  Google::Search::Image.new(:query => 'Cookies').each do |image|
    file.write %(<img src="#{image.uri}">)
  end
end
