example lookup for "engine shroud" by typing "shroud"

http://localhost:8080/motorbike_parts/?word=s
["back rest", "foot peg", "handle bar", "seat", "spokes", "spring"]
http://localhost:8080/motorbike_parts/?word=sh
["leg shroud", "hub", "wind shield", "foot peg", "engine shroud", "back rest"]
http://localhost:8080/motorbike_parts/?word=shr
["wheel rim", "leg shroud", "engine shroud", "handle bar", "hub"]
http://localhost:8080/motorbike_parts/?word=shro
["engine shroud", "leg shroud", "hub", "back rest"]

It handles mispellings pretty well

["shrew", "ferret", "hare"]

Great fun to play with, and not particularly slow!
