getting a "too many searches from your domain" message when trying to search the forums instead of posting already answered questions.
Perhaps you guys may consider actually paying for google search or doing it yourselves, because the stingy free limit imposed by google is breaking your ability to provide support to your customers.

I know it isn't a solution to the site issue, but you can also search directly from google.

Use something like site:forum.nusphere.com too many searches

True enough, but still ...
