Subject [jira] Commented: (LUCENE-2504) sorting performance regression
Date Mon, 13 Sep 2010 19:29:33 GMT


Robert Muir commented on LUCENE-2504:

bq. Yep, should be fine. Is there an upper bound on how long collated terms can be?

There isn't, but...

I can't promise (but i'll verify), i think actually a single 0xff might do, for the major

* its invalid in utf-8
* its technically valid, but unused (reset byte) in bocu-1
* collation keys i understand are a modified bocu, likely unused there too.

so its like a NaN sentinel, if someone is doing something very wierd, maybe it wont work,
but in general, i think it will work. ill check.
