Instance Method Details

#search(options = {}) ⇒ Object

All you need to do is specify a :type => ‘web’ or :type => ‘local’ or whatever type of search you want to do. And you also need to pass a query through :q => “Awesomeness”. Any other optional parameters can be specified with a hash key value pair in the method call of search ie

search(:type => ‘web’, :q => ‘somequery’, :rsz => ‘big’) this would return a web search with the query ‘somequery’ and return a big resultset
