Dear Andi,
I like to request a new feature for the next version of PyLucene. Lucene
already comes with a collation library but PyLucene doesn't wrap it.
Collation is required for language depending sorting of search results. [1]
I've attached a working patch for the feature request.
>>> from lucene import *
>>> initVM()
<jcc.JCCEnv object at 0x7f326926e0d8>
>>> collator = Collator.getInstance(Locale("de"))
>>> keyanalyzer = CollationKeyAnalyzer(collator)
>>> keyanalyzer
<CollationKeyAnalyzer:
org.apache.lucene.collation.collationkeyanaly...@510dc6b5>
Thanks
Christian
