I just created a custom search engine @ Google for SI2012 incorporating
- the User guide
- the SDK guide
- the Mental Ray 2012 docs
- the Composite 2012 docs
- the MatchMover 2012 docs.

Nothing fancy, but it might be helpful to someone else also
(probably not as it has much to do with my own preferences of searching),
so I thought I post it here:
the address is http://tinyurl.com/SI2012search
It's the free CSE version, so it's ad-based (sorry about that).

I haven't tested it much, but there should be no problems.
If there are, please let me know...

Good idea, thanks

Here's how to add that custom search engine as a
search provider in IE.
