Match multibyte characters in boolean mode

[receiver]

Hi, i really surfed a lot to find a solution but didn't find anything that could help me.

 

I need to search multibyte characters and all others(chinese russian etc).

 

this only matches english words but doesn't match multibyte characters even if they in utf-8 tabel or in latin1 swedisch ci

 

I can retrive(insert to db and retrive with no problems) multibyte characters to show with no problems but search doesn't work :

 

MATCH(s.keyword,s.desc,s.title,s.url,u.usern) AGAINST('$q' IN BOOLEAN MODE )  - just does not match!

 

inside a latin1 table they look like this "кÑперт кÑперÑ" but show on php allright. in table utf-8 they look clean like this: 'Эксперт'. but still cant retrive them i mean search using boolean mode or any other mode.

 

anyone can help me with this , ?

Anyways, thank you! for the reply, but I can retrieve  data from db that are multibyte characters example like "select from where sometable='Эксперт ксперт'" etc. This should mean that characters are supported? right, but cant use in "match against".

 

 

this does notwork: MATCH(s.title) AGAINST('$q' IN BOOLEAN MODE ) (cant find any results at all )

this works: where s.title='$q'

 

my php ini:

 

;mbstring.language                  = Japanese
;mbstring.internal_encoding         = EUC-JP
;mbstring.http_input                = auto
;mbstring.http_output               = SJIS
;mbstring.encoding_translation      = Off
;mbstring.detect_order              = auto
;mbstring.substitute_character      = none;
;mbstring.func_overload             = 0

 

any suggestions?

tried this: s.title like '%$q%'  this works but why isn't the boolean mode  working?

Thank you for your reply!

I could not understand what does the workaround options mean. Can't see any workaround? just explanes the search relevance theory.

Yes my tabels are MyISAM,  MySQL charset: UTF-8 Unicode (utf8).  tabel is  full text index, even tryed without boolean mode and worked for regular eng characters.

 

in "match agains" mode can not see the multibyte characters at all or why doesn't it return any results. if I search this text "Эксперт Эксперт ксперт legos mangé manager" it appears in case: legos or mangé or mangésomerandom or manager not in case Эксперт Эксперт ксперт, ( about the third word (mangésomerandom- no word like that) makes the character é look more like some placeholder or space, anyways does not return results in case "mang"). I tried adding "" to search but nothing.

 

Only way I can think right now is to use like method separately for multibyte searches.

 

anyone can suspect anything? what could be the problem.

I started getting some result by searching Arabic and different texts in Russian. Dont know why my first Russian text didn't appear. other languages don't act like English in search, probably  I don't know the languages no enough, anyways let see what happens. Some like Armenian still don't show nothing.
