Subject [jira] Commented: (SOLR-1804) Upgrade Carrot2 to 3.2.0
Date Wed, 21 Jul 2010 19:36:52 GMT


Stanislaw Osinski commented on SOLR-1804:

Essentially, the dependency on the smart chinese is optional in a sense that the lack of it
will degrade the quality of clustering in Chinese, but will not break it. Let me see if I
can make it optionally loadable in LuceneLanguageModelFactory too.

I think we could handle this in a similar way as in Carrot2: attempt to load chinese tokenizer
and fall back to the default one in case of class loading exceptions. The easiest implementation
route would be to include smart chinese as a dependency during compilation of the clustering
plugin with an understanding that the library may or may not be available during runtime.
Is that possible with the current Solr compilation scripts?
