|
|||
* LUCENE-3340: Fixed case where IndexWriter was not flushing at
|
||||
exactly maxBufferedDeleteTerms (Mike McCandless)
|
||||
|
||||
* LUCENE-3358: StandardTokenizer wrongly discarded combining marks attached
|
||||
to Han or Hiragana characters, this is fixed if you supply Version >= 3.4
|
||||
If you supply a previous lucene version, you get the old buggy behavior
|
||||
for backwards compatibility. (Trejkaz, Robert Muir)
