MSN and Ask

Does anyone know how to get more than 10 results (ideally 100) from either of these by altering the URL string? I know how to do it in Google (&num=100) and Yahoo (&n=100) but MSN and Ask seem to use a cookie rather than URL string. It's making scraping a lot more difficult than it needs to be. Any help appreciated.

In MSN the only way is to go into the options, the maximum number of results you can have it return is 50

I just looked up ask, and it seems that you can't get more than 10 results

Generally speaking google has the best content anyway, MSN ans Ask are rather gash search engines imo
