ASPDidYouMean - the search query spell checker.

Software Component Overview:

"Google" style search spelling suggestions & Improved search results

Compatible with ASP & PHP

ASPDidYouMean provides international spell checking for search queries. You can easily integrate this functionality with your web site, intranet or portal.

The component closely resembles the "Did You Mean...?" feature seen on Google and Yahoo!

ASPDidYouMean is used on major public search engines, and is load balanced and tested for such heavy use. It is, however, also very much at home on small web sites & intranets. 

It supports over 10 Languages.  You may also build custom dictionaries & link it in to databases.

This Active-X Server Component is fully documented and has a free 30 day trial.
