Description Minh Nguyễn 2006-04-29 06:47:11 UTC

At the Vietnamese Wikipedia, most pages (and their titles) include words with
precomposed, accented Unicode characters. (See [[Precomposed character]] and
[[Vietnamese alphabet]].) However, users who search for articles at the
Vietnamese Wikipedia often enter queries with the unaccented base characters,
with the expectation that MediaWiki will understand their query. MediaWiki
neither strips combining characters (Bug 1836) nor converts the precomposed
characters in existing pages to their base ASCII characters (i.e., ô→o and ậ→a)
when searching page titles or text, so the search feature consistently returns
disappointing results.

Steps to reproduce:
1. Search for "viet nam" or "Viet Nam" (without the quotes) at the Vietnamese
Wikipedia

Expected results:
[[vi:Việt Nam]] is the first result, or at least somewhere in the results.

Actual results:
"Việt Nam" is nowhere to be found.

Please see also Bug 1836, Comment 3:

> Perhaps the search function should ignore diacritics in article titles when the
user has entered a query that contains no diacritics. If the user has entered in
diacritics, the software should respect that. It would also be nice if there
were a MediaWiki message in which a list of diacritics could be customized per
wiki or locale, since different languages distinguish letters and diacritics
differently.

Comment 3 Minh Nguyễn 2006-04-30 00:19:38 UTC

This is not the same as Bug 1836. That bug is for ignoring combining (but
separate) diacritical characters in Unicode; this bug is for converting
precomposed characters, which might be a lot more complicated.

Comment 4 Brion Vibber 2006-04-30 00:23:52 UTC

No, that's the same thing.
