Search Facility

I have a website which I would like to add a search facility to. I would like it to work so that when you do a search it lists all the relevant pages with a link to each of the pages. Each entry in the list of results should list the title of the page based on the <title> tag and use the meta description or a small portion of the text from that page under the title. You can use Google’s search facility to implement this or another technology, but whatever you use it must not be branded with another companies logo.
