Search correction
Hi, all,
Most of us should have some experience about inputing an incorrection
keyword in google or some other search engine. When this happens, google can
celverly suggest you another query keyword(not google suggestion).
e.g. you intend to search for redhat, instead you type rdehat, the
google will tell you Did you mean:
*redhat*<http://www.google.com/search?hl=en&newwindow=1&ei=0DUnS98JzYaQBbSTyfgM&sa=X&oi=spell&resnum=0&ct=result&cd=1&ved=0CAYQBSgA&q=redhat&spell=1>
How can i implement this feature in my own system?

I recall reading Google does it based on statistical analysis of what words
users type. For example if I search for "googl" and then my next search is
for "google" that is stored. Next time someone types "googl", "google" is
suggested.
Sorry, I don't have a source to link you to on that though.
Cheers,
Chris

Thanks Simon, i used a similar approach as SpellChecker to do search
suggestion.
I'll try that in search correction.

Weiwei,
Lucene Contrib offers a Spellchecker package that might help you with
your application. The spellchecker takes a dictionary of terms (build
from your search index or from some other text resource) and builds a
suggestion index from those terms. Internally terms are indexed as
ngrams. You can pass in a possibly missspelled term and a distance
measurement function to build up a suggestion array from the
suggestion index.
I have no comparison how good it works with chinese text though.
