Re: [discovery] An idea to improve the clickthrough rate

It looks like a bug... As Trey said it happens sometimes. But for peripheral neuritis it's not the case, the highlighter decided to highlight a partial match ( *peripheral* neuropathy ) instead of the full match to the redirect. I think that when there's a single match to a word in the title any other matches (even better ones) to redirects, categories or headings will be ignored. We will have to review the highlighter configuration to fix this issue. Le 30/11/2015 15:50, Trey Jones a écrit : Though it isn't exactly the same, this reminds me of our discussion back in Aug/Sep about Corn and Maize, much of which is on Phabricator: https://phabricator.wikimedia.org/T110571 . The behavior you want happens sometimes. Searching for "usually" gives as the first result: Convention (norm) (redirect from Usually) "difficult": Difficulty (redirect from Difficult) "corn", among its many odd behaviors, gives: Maize (redirect from Maize corn). I think there's some sort of ranking going on for redirects that can put a partial match above an exact match (hence "Maize corn" instead of "corn" as the redirect shown). More relevant to your example, I think that if there's a match on one or more search terms in the redirected-to title, it blocks redirected-from titles from being shown. Searching for "neropathic" gets a spelling correction to "neuropathic", which gives as the first result: Peripheral neuropathy (redirect from Neuropathic). David may know more about either of these cases off the top of his head. (But maybe not, since it was a while ago, and I recall that it was very messy, and we declined to work on it then.) So, at the very least, the control group would at least sometimes have a chance of getting the test behavior because we do that now under certain circumstances. Another option is to consider this a bug fix so that we have consistent behavior whenever there's an exact match of the query to a redirect title, regardless of partial matches to the redirected-to title or higher-ranked redirects. It would also be interesting to know how often queries get redirected results, and how often they show the redirects—either in general, or as part of any A/B test. —Trey Trey Jones Software Engineer, Discovery Wikimedia Foundation On Sat, Nov 28, 2015 at 3:40 AM, Oliver Keyes <okeyes(a)wikimedia.org> wrote: _______________________________________________ discovery mailing list discovery(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/discovery _______________________________________________ discovery mailing list discovery(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/discovery
