Yahoo Limitation

does yahoo limit the search query per day?

I ran a script to search around 400 keywords on yahoo. At first, it giving me the result, but after a while it stop working. I use both yahoo and google, and google works just fine. Is there any limitation on yahoo that allows you to submit only certain number of query per time period?

Thanks,

I don't know the answer, but I would assume their is some limitation.
I wonder how other people write scripts to go through yahoo and get results? They must run into the same problems, how did they get around it?

use proxy servers, If anything they are going to block your ip address.
