Subject [jira] Commented: (LUCENE-2023) Improve performance of SmartChineseAnalyzer
Date Fri, 30 Oct 2009 18:01:00 GMT


Robert Muir commented on LUCENE-2023:

DM, personally I don't see the slowness as a bug... though I am very aware word segmentation
speed is really important to chinese users.

but if all the other devs jumped up and said yeah its really critical to be in a bugfix release,
i'd backport it to java 1.4

in my opinion its just an improvement.
