Understanding the Google API Response
While the Google API grants you programmatic access to the lion’s share of Google’s index, it doesn’t provide all the functionality available through the Google.com web site’s search interface.
Can Do
The Google API, in addition to simple keyword queries, supports the following special syntaxes [Section 1.5]:

The 10-Result Limit
While searches through the standard Google.com home page can be tuned [Hack #1] to return 10, 20, 30, 50, or 100 results per page, the Google Web API limits the number to 10 per query. This doesn’t mean, mind you, that the rest are not available to you, but it takes a wee bit of creative programming entailing looping through results, 10 at a time [Hack #51].
What’s in the Results

true/false) value specifying whether or not results were ...
