basic question: how do i insert a string on google?

[swap]

Hey there.I want to make a php script that gets a few words from the user and then add some search rabbits and inserts it into google.how do i insert a string on google?is there a way to construct a google url from a search string? how?like... i want to make a google_search() function that has the search string as a paremeter.I've never used it myself but it sounds like you need the Google API:http://www.google.com/apis/Should find some relevant info there if nothing else.yep... i've been searching about this and i ended up reading about this google API...It sounds cool but i can only perform 1000 queries a day.i am using http://www.google.com/ie page to get a simple formated search result.question... i am writing this script in with i get a google result page and load it using php's file() function, then i do whatever i want with the results...is it anything wrong with that? am i allowed to do that king of usage of it?Its against google tos to query thier servers with any method other than an API.
