Parsing Google's search results

I'm "working" on a data mining project and I've chosen to parse Google search results. Now before I actually start, I want to consult you - experienced folks. I did a bit of research on how Google delivers results and I analyzed structure of a re开发者_Python百科sult page. That's all alright, I've already figured out regexes and data structures I'll use.

In between I encountered their CAPTCHA because I was searching too fast; oh, the irony. I've also discovered that they limit results to 1000 actually. Now, is there any way I could avoid those peripeties, perhaps slowing the rate of url fetching to solve the first one or reporting when encountering CAPTCHA so that it waits for my input; that might do it, but what about the other one ? Does Google provide some kind of an API that I can use for a workaround? I couldn't find one on their code.* page.

There is a Custom Search API.

It returns results in json or XML, so you won't even need to use regexes. However, you do need to pay for more than 100 searches a day.

What exactly are you trying to do? Maybe there is a better way to accomplish it.

Always look on CPAN first!

If someone hasn't already solved your problem, chances are it's a weird one :-)
