Table indexing by membership in a set of multiple values

As a MagnetoDB user, I want to create an index on a column that contains a set of values so that I can retrieve the row using a "set membership" operator.

Example scenario…
Rows:
{1, 2, 4, 8, 16, 32, 64, 128, 256}, “powers of 2”
{1, 3, 9, 27}, “powers of 3”
{1, 4, 16, 64}, “powers of 4”
{1, 5, 25}, “powers of 5”

Query for “contains 16” returns “powers of 2” and “powers of 4”
