The Quick Search works with partial words or phrases, so try using a shorter search text.
If you cannot find a coaster by its name, try searching for the amusement park where it is located. Then you can browse through a list of roller coasters located in that park.
You may also enter any location name into the Quick Search -- names of counties, states, cities and even postal codes may be used.
Try using the Advanced Search. It has additional options like status, type, etc. that are not available through the Quick Search.
