Spell Checker in Nutch 1.0

Can anyone tell me how to implement spell checker in nut开发者_开发技巧ch 1.0?

Can anyone tell me how to use the spell-check query plugin available in the contrib \ web2 dir (and even the rest of the plugins too)? Is it similar to enabling the nutch-plugins?

First hit at google (`nutch spell checker') and located on the apache nutch project pages...
