DESCRIPTION

Google::Search allows you to programmatically query the Google search-engine at www.google.com. It is currently in the alpha stage and the interface is liable to change at any time.

CLASS METHODS

Search.new(key): This constructs a new Google search object. The key parameter is the key that Google assigned to you when you registered for the Web API download. If you don't yet have a key, go to Google and obtain one.

INSTANCE METHODS

Search#search(query, start, max, filter, restrict, safe, lr, ie, oe)

This performs a standard Google query search. Only the query parameter is mandatory.

The meaning of the other parameters can be obtained from section 2.1 of the APIs_Reference.html file that came with your Google API archive.

This method returns a Hash, the keys of which are described in section 3.1 of APIs_Reference.html.

The resultElements element is, itself, a Hash, the elements of which are described in section 3.2 of APIs_Reference.html.

Search#spell(phrase)

This attempts to perform a Google spell-check on phrase. If Google has no spelling suggestions to make, nil is returned. Otherwise, a String is returned.

Search#cache(url)

This attempts to retrieve the cached Google copy of the page corresponding to url. If Google has not cached the URL in question, a page containing a message to this effect will be returned by the search-engine.

This method always returns a String.
