In an extension, I'd like to detect when the "Go" button has been used to jump directly to an article that exists. Any ideas how to do this? Here is what I have tried so far:

- The Special:Search page (file specials/SpecialSearch.php) does an immediate redirect to the target, with no hook provided. - There is a hook SpecialSearchNogomatch that detects the use of the "Go" button but only when the target doesn't exist. That's the opposite of what I need: in my case, the target does exist. This hook is called too late anyway (after the redirect). - The hooks SpecialSearchResults and SpecialSearchNoResults do not fire in this situation - Maybe use a hook in the Title or Article class, but how to detect only the Go button? I don't want to include articles that have been visited by URL or by clicking a wiki link.

By brute force, I could probably make my extension run on every page load (ugh), tracking if I'm on Special:Search with a query string parameter "Go=go", and then use the SpecialSearchNogomatch hook to exclude searches that fail. But that feels like an inefficient hack.

Thanks for any ideas.... DanB
