Subject [jira] Commented: (SOLR-2276) Support for cologne phonetic
Date Tue, 28 Dec 2010 14:54:46 GMT


Robert Muir commented on SOLR-2276:

bq. Seems ColognePhonetic will be supported in Apache Commons Codec 1.4.1.

Thanks for your patch Marc. Has there been any discussion on a tentative release date for
When this happens I'll be happy to add it.

Besides, do you think it is a good idea to allow a fully qualified class name as "encoder"
in PhoneticFilterFactory? Extending solr by a custom phonetic filter could be much easier
for developers.

I think the reason its not done with reflection might be historical, before all tokenstreams
were reused?
But I still think its a good idea to avoid reflection when possible, so I think we should
keep the statically built map.

However, if you supply a string thats not in this map, I don't think it would hurt to try
to reflect the name
before throwing an exception, as in this case you would only get an exception anyway.
