Simon Willnauer commented on LUCENE-2094:
-----------------------------------------
bq. I think changes other than that should be another issue, a sub-issue, or a
linked issue? As it stands, Robert's patch, having the same name as Simon's,
makes it appear that it supersedes the prior with the same name. It is
confusing without the context of reading the thread.
+1 - I created LUCENE-2099 for that purpose and added Roberts latest patch to
it.
I will like those two in a second.
bq. By using LUCENE_CURRENT, it means that the most recent behavior should
always be used. That might change in the future. If it does, then it would
silently invalidate an index.
This has many reasons. The most important one is that the version will not
affect those sets as the pass false to ingoreCase and we have full control over
the stopwords. But I agree this would be more "secure" if it would use
Version.LUCENE-31 just to make sure nobody changes the internal behavior of
CharArraySet. I still would expect anybody changing the behavior of this class
to revise their usage.

> CharArraySet does lowercaseing if created with the correspondent flag. This
> causes that String / char[] with uncode 4 chars which are in the set can not
> be retrieved in "ignorecase" mode.
