Sylvain Lebresne updated CASSANDRA-4257:
----------------------------------------
Attachment: 4257.txt
That was kind of a typo. When 2ndary indexes was used, the code was expecting
that a column that had a lesser-than clause on it, also had a greater-than one.
Simple patch attached to fix. I've pushed a regression test to the dtests too.
