Plugin? what? Manually? How? (Soma links please)
Assuming you are using mysql the easiest way is probably mysql's fulltext search (because you don't need to worry about running indexing tools, having a search daemon running etc.)
should add that this lacks some of the sophistication of other solutions and that the reason I stopped using it on one app was because it was getting pretty sluggish with a couple of hundred thousand documents.

In Nick Plante and David Berube's book "Practical Rails Plugins" Chapter 16 talks about implementing the plugin Sphinx to do Full Text Search.
