welcome to WebmasterWorld, complete!

you might want to familiarize yourself with the terms of service for the search engines in which you are interested.
they typically frown on scraping search results using "automated methods".

some search engines provide an API which may be sufficient for your requirements:
DuckDuckGo API - [duckduckgo.com...]
Yandex.XML - [api.yandex.com...]
