If you mean something to the effect of typing:
'wp searchterms gohere'
to search, say, Wikipedia (or whatever else you can wrangle an url for), then I know that at least Chrome, Firefox, Konqueror and Opera support it.
In Chrome you can customize it via
Options > Default Search > Manage
In the others, I think it's handled through bookmarks (add a keyword to the bookmark properties, and throw a %s in the link address for the search term).
