Lex Lythius commented on CASSANDRA-4511:
----------------------------------------
Note that CQL for Cassandra 2.x documentation (page 48) still says:
{quote}Currently, you cannot create an index on a column of type map, set, or
list.{quote}
whereas CREATE INDEX syntax is accurate:
{code}
CREATE CUSTOM INDEX IF NOT EXISTS index_name
ON keyspace_name.table_name ( KEYS ( column_name ) )
(USING class_name) (WITH OPTIONS = map)
{code}
> Secondary index support for CQL3 collections

> We should allow to 2ndary index on collections. A typical use case would be
> to add a 'tag set<String>' to say a user profile and to query users based on
> what tag they have.
