I'm less sure that re-ordering would do the right thing for French. Presumably the French stemmer knows about accented characters and uses them. We should test and make sure. Maybe we need custom folding only for "unusual" accents in any given language (they are all unusual for English). We can test French the same way we tested English, though, and be sure. —Trey Trey Jones Software Engineer, Discovery Wikimedia Foundation On Wed, Aug 10, 2016 at 10:48 AM, David Causse &lt;dcausse(a)wikimedia.org <mailto:dcausse@wikimedia.org>> wrote: Thanks Trey! this will certainly greatly improve the intitle keyword as it uses the field with stems for filtering and hopefully will find pages that were ignored because of this filter ordering (e.g. intitle:louys can't find User:Louÿs currently). I think I'll do the same for French which suffers from the same problem. IMO we should continue to work on this for other languages while we try to switch from asciifolding (latin letters only) to icu folding. We may require some guidance on some languages where diacritics removal can be counter productive and maybe blacklist some letters (e.g. for finnish: is it appropriate to fold Ä or Ö for example?) Note on accent folding: cirrus tries to always prefer exact matches. Searching for élément should always prefer élément over element. Users that prefer exact matches can always force cirrus to discard stems by wrapping the word in double quotes, e.g. "élément".
