----------------------------------------

             Summary: Iterator and example to support intersection of document-partitioned
index terms by ranges with lower and upper bounds.
                 Key: ACCUMULO-1682
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1682
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Corey J. Nolet
            Priority: Minor


The current IntersectingIterator seeks to discrete terms that are encoded into the column
families to find all column qualifiers that share all of the discrete column families of interest
(with the additional ability to negate some of the column families). Looking at the current
IntersectingIterator code, it should be possible to return all column qualifiers with a column
family within a given range.

An example of this is finding all terms where NAME=Joe and (AGE>=30 && AGE<60)
and STATE!=MD. If an example is provided, numerical types like the age could easily be encoded
using the new Lexicoders.
