Custom "Search Google for" type of functionality on context menu using Automator?

Can I use automator to add a context men (right click) item that adds a selected highlighted text from a browser or document to the address field of a browser by adding it at the end of a custom URL that I can specify beforehand? Somewhat similar to the Search Goggle context functionality that currently sends highlighted text to a google search on the browser?

Any ideas? thx
