> I can do queries for collection keys/values as detailed in http://www.datastax.com/dev/blog/cql-in-2-1 without problems. Even without having a secondary index on the collection it will work (with {{ALLOW FILTERING}}) but only as long as the query is performed through a *secondary* index. If you go through PK it won't. Of course full-scan filtering query is not allowed.
> As an example, I created this table:
> {code:SQL}
> CREATE TABLE test.uloc9 (
>     usr int,
>     type int,
>     gb ascii,
>     gb_q ascii,
>     info map<ascii, text>,
>     lat float,
>     lng float,
>     q int,
>     traits set<ascii>,
>     ts timestamp,
>     PRIMARY KEY (usr, type)
> );
> CREATE INDEX uloc9_gb ON test.uloc9 (gb);
> CREATE INDEX uloc9_gb_q ON test.uloc9 (gb_q);
> CREATE INDEX uloc9_traits ON test.uloc9 (traits);
> {code}
> then added some data and queried:
> {code}
> cqlsh:test> select * from uloc9 where gb='/nw' and info contains 'argentina' allow filtering;
>  usr | type | gb  | gb_q  | info                                     | lat          | lng          | q | traits             | ts
> -----+------+-----+-------+------------------------------------------+--------------+--------------+---+--------------------+--------------------------
>    1 |    0 | /nw | /nw:1 | {'ci': 'san antonio', 'co': 'argentina'} | -40.74000168 | -65.80000305 | 1 | {'r:photographer'} | 2014-11-04 18:20:29-0300
>    1 |    1 | /nw | /nw:1 | {'ci': 'san antonio', 'co': 'argentina'} | -40.75799942 | -66.00800323 | 1 | {'r:photographer'} | 2014-11-04 18:20:29-0300
> (2 rows)
> cqlsh:test> select * from uloc9 where usr=1 and info contains 'argentina' allow filtering;
> code=2200 [Invalid query] message="No indexed columns present in by-columns clause with Equal operator"
> cqlsh:test> select * from uloc9 where usr=1 and type=0 and info contains 'argentina' allow filtering;
> code=2200 [Invalid query] message="No indexed columns present in by-columns clause with Equal operator"
> {code}
> Maybe I got things wrong, but I don't see any reasons why collection filtering should fail when using PK while it succeeds using any secondary index (related or otherwise).
