Like someone else said before me, you can get unparsed wikitext through 
prop=revisions&rvprop=content . If you want HTML without the sidebar and 
all that, you can get it with

index.php?action=render&title=Foo

You can actually search Wikipedia through the API:

http://en.wikipedia.org/w/api.php?action=query&list=search&srsearch=Foo&srwhat=text&srlimit=5
(gets a list of 5 pages containing 'Foo')

http://en.wikipedia.org/w/api.php?action=query&generator=search&gsrsearch=Foo&gsrwhat=text&&gsrlimit=5prop=revisions&rvprop=content
(gets the contents of those pages)

You can also get search suggestions in the OpenSearch format with 
http://en.wikipedia.org/w/api.php?action=opensearch&search=Te
