Description Gildas 2007-04-16 22:35:48 UTC 
Hello everybody !

I'm french, i use the mediawiki for myself.

I have trouble with it:

for example:

i made a page "la Manoeuvre d'ortolani"

i wrote some words:

"la manoeuvre d'ortolani est destinée à tester la hanche des nourissons"

well, ok, it's in french ;-)


the big bad trouble is:

when i search the word ORTOLANI, the mediawiki find ... nothing because for
mediawiki 
"D'Ortolani" is ONE WORD but in french "D'ortolani" is a contraction of TWO WORDS
"DE + ORTOLANI" = "D'ORTOLANI"

I'm tired to modified all the page by writing this for trying to correct this:

"Manoeuvre d'ortolani (ortolani)"

could you try to fix it ?

thank you

sorry my english is ... bad really.

The search engine use mysql Full-Text search engine, according to
the documentation [1] the apostrophe ' and underscore _ are considered
as part of the word.

The bug got fixed in mysql 5.1.6 [2]

Marking bug as 

[1] http://dev.mysql.com/doc/refman/5.1/en/fulltext-fine-tuning.html
[2] MySQL bug report : http://bugs.mysql.com/bug.php?id=14194
Comment 2 Aryeh Gregor (not reading bugmail, please e-mail directly) 2007-05-06 00:52:52 UTC 
That's MySQL fulltext.  Wikimedia doesn't use that, so I doubt the bug was filed
with that in mind.  This should be filed against Lucene, presumably.  I don't
know if this is fixable on our end, though?
Comment 3 Antoine "hashar" Musso (WMF) 2007-05-06 00:54:53 UTC 
Lucene doesn't have this problem. reclosing.
Comment 4 Andre Klapper 2013-03-26 11:24:34 UTC 
[Merging "MediaWiki extensions/Lucene Search" into "Wikimedia/lucene-search2", see bug 46542. You can filter bugmail for: search-component-merge-20130326 ]
Comment 5 Akeron 2013-11-29 11:01:59 UTC 
This bug is still here

For example : https://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=default&search=Arc-en-Ciel&fulltext=Search  "Arc-en-Ciel" doesn't match any "L'Arc-en-Ciel" (with L') directly.

Compare with a search "L'Arc-en-Ciel" https://en.wikipedia.org/w/index.php?search=L%27Arc-en-Ciel&title=Special%3ASearch&fulltext=1

The "L'" should not be a part of the word, its another word.
Comment 6 Andre Klapper 2013-12-02 11:26:54 UTC 
Akeron: Could you please file a new bug report? This one got closed six years ago and nowadays issues for this problem to happen again are likely different. Thanks!
