Search result RSS feeds can help you monitor a certain search query, and let you know when new results appear for the query.
All search result pages have an RSS link embedded in them. Recent versions of modern browsers, such as Internet Explorer and Firefox, have built-in features that notify you when an RSS feed you're subscribed to changes.
