On the internet now, you can find documentation for three DIFFERENT Google 
search APIs. The first API that they released used an approach called SOAP 
which returned results in an XML format. This is what the documentation you 
were seeing at http://code.google.com/apis/soapsearch/api_faq.html#gen12 is 
referring to. The SOAP Search API would return up to 1,000 results for a search 
term, but it also had a limit of 1,000 queries per day, but it was discontinued 
in 2008 or 2009.

The second rendition of a Google search API was originally called the AJAX 
Search API. It did not have a hard limit on the number of requests you could 
send per day, but it was throttled and restricted in other ways to discourage 
SEO applications from using the service (e.g., it would only return up to 64 
results for a normal query, 100 for Custom Search Engine query). This is what 
you were seeing demonstrated at 
http://code.google.com/apis/ajax/playground/#the_hello_world_of_general_search 
. This API has been expanded for use beyond AJAX, so it became called simply 
the WebSearch API, and you can find documentation at 
http://code.google.com/apis/websearch/docs/ . You will notice at the top of 
that page, though, that this API has been deprecated since November 2010. This 
means that, while it still works and Google will still maintain it, it is 
scheduled for shutdown no later than November 2013.

The WebSearch API is being succeeded by the Custom Search API, which is really 
designed to interface a Google Custom Search Engine (see 
http://www.google.com/cse for more information) rather than simply search the 
general web. There are advantages and disadvantages to this API. Two big 
advantages are that it will return up to 100 results, and those results will 
generally be pretty good because CSE's are designed to be "curated" - that is, 
you set it up, pick the sites you want to search, and so you don't get a lot of 
garbage results. But there are also a couple of big disadvantages to it. For 
instance, the CS API will not search the general web; it must be coupled with a 
CSE, effectively rendering it useless for SEO applications and general search 
functionality. And the big disadvantage is that it is actually limited to only 
100 requests per day. You can request more quota than that via the APIs 
Console, but the criteria on which the increased quota is granted - and the 
timeframe in which it will be processed - are absolutely unclear. You can sign 
up for the CS API and find the documentation for it and a number of other 
Google APIs in the API Console at http://code.google.com/apis/console

Hope this helps clear things up a bit.
