OK, the winner is Yahoo Spelling Suggestion (which uses Yahoo API). This gives your site the possibility to suggest exactly what Yahoo Search suggests :cool: Awesome, I would say!

Here is a short summary about using it, if you guys want to use it too: it requires a Yahoo API key, which can be got free. It is limited to 5000 queries per day, so I suggest caching the suggestion (which I implemented, as my site has more then 5000 searches...

google custom search is not good for me... i want to display the results in my layout, using some special boxes....

anyway, am now trying levenstein, soundex, and also yahoo api. thanks.

Hello, I want to add the 'did you mean' feature (like on Google) on my shareware site, where a lot of users have mistypes, and they get 0 results... so they exit the site very fast. Do you have any idea how I could implement such a thing? Does it require a dictionary or something? I found some scripts, but none of them gave relevant results... just stupid, irrelevant suggestions. Any help would be appreciated... sample code would be awesome.
