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.
