Accent Insensitive Search

Hi All,

I need to implememnt Accent Insensitive Searchin my application.

 

Simple example is Kraków search should also bring Krakow also in search results.

 

I have seen many threads discussing sloution with SOLR, But I dont want to use SOLR in my application for only this feature.

 

Any suggessionas?

 

 

Regards,

Aamir Yaseen

Note that ISOLatin1AccentFilter converts accent characters only from
ISO-8859-1 character set. Which means that if you need to convert
accents of eastern European languages you need to write your own
accent filter.

As pointed out previously, you need to transliterate your input using  
something like ISOLatinFilter or such.

For example, searching for 'aaiun' should return 'Aaiún' and vis-versa:

http://svr225.stepx.com:3388/search?q=aaiun
http://svr225.stepx.com:3388/el-aaiun

Sean M. Burke's Unidecode provides an extensive transliteration of  
Unicode into ASCII:

E.g.:

Москва́	Moskva
北京	beijing
Ἀθηνᾶ	Athena
서울	seoul
東京	dongjing
京都市	jingdushi
नेपाल	nepaal
