>  I'm playing with Cassandra 3. I added a secondary index on a column of integer, then
I want to do a range query. First it threw an error:
> {code}
> InvalidRequest: code=2200 [Invalid query] message="No supported secondary index found
for the non primary key columns restrictions"
> {code}
> So I added 'Allow Filtering'
> {code}
>     cqlsh:mykeyspace> SELECT * FROM test ;
>     id | id2 | age | extra
>     ----+-----+-----+-------
>       1 |   1 |   1 |     1
>       2 |   2 |   2 |     2
>     (2 rows)
>     cqlsh:mykeyspace > CREATE INDEX test_age on test (extra) ;
>     cqlsh:mykeyspace > select * FROM test WHERE extra < 2 ALLOW FILTERING ;
>      id | id2  | age | extra
>     ----+------+-----+-------
>       1 |    1 |   1 |     1
>       2 | null |   2 |  null
>     (2 rows)
> {code}
> My schema is:
> {code}
>     CREATE TABLE mykeyspace.test (
>     id int,
>     id2 int,
>     age int static,
>     extra int,
>     PRIMARY KEY (id, id2)
>     ) 
> {code}
> I don't know if this is by design or not, but it really does look like a BUG to me.
