Aad, Are you trying to check the spelling of English words by Dutch children? Then, Phonetix or any of these other solutions may not be perfect. >From my little knowledge of Dutch, a "g" is some sort of velar fricative (pronounced at the back of throat). And "ch" in english is also a velar fricative. You have to hope that the soundex/metaphone rules are broad enough to be used by both languages.
Interesting little problem. No J2EE libraries to call, just static String convertToSoundex(String word) to implement. Ah if only I could do more of that sort of coding. Ciao, Jonathan O'Connor XCOM Dublin Kelvin Tan <[EMAIL PROTECTED]> 09/02/2005 13:03 Please respond to "Lucene Users List" <lucene-user@jakarta.apache.org> To Lucene Users List <lucene-user@jakarta.apache.org> cc Subject Re: sounds like spellcheck [auf Viren geprueft] Hey Aad, I believe http://jakarta.apache.org/lucene/docs/contributions.html has a link to Phonetix ( http://www.companywebstore.de/tangentum/mirror/en/products/phonetix/index.html ), an LGPL-licensed lib for phonetic algorithms like Soundex, Metaphone and DoubleMetaphone. There are Lucene adapters. As to the suitability of the algorithms, I haven't taken a look at the Phonetix implementation, but if http://spottedtiger.tripod.com/D_Language/D_DoubleMetaPhone.html is anything to go by (do a search for "dutch"), then it should meet your needs, or at least won't be difficult to customize. Is that what you're looking for? k On Wed, 09 Feb 2005 13:23:57 +0100, Aad Nales wrote: > In my Clipper days I could build an index on English words using a > technique that was called soundex.
