First of all you should sanitize you input as @Nikita commented. If you want to accept JavaScript and only disable alert you can replace the window.alert function.

window.alert = function() { /* do nothing here */ }

Now calling alert won't do anything.

When presenting the search results back to the user you need to ensure you HTML encode the output so the user would see the script rather than it being executed.
