Description

Because the GT/GTE/LT/LTE operators generate Slice restrictions, when the index is on a clustering column and a range predicate is used, restrictions are not allowed on any following, non-indexed clustering columns.

cqlsh> create table ks.t1 (k text, c1 int, c2 int, c3 int, v text, primary key (k,c1,c2,c3));
cqlsh> create custom index on ks.t1(c2) using 'org.apache.cassandra.index.sasi.SASIIndex';
cqlsh> select * from ks.t1 where c1 = 1 and c2 > 0 allow filtering;

 k | c1 | c2 | c3 | v
---+----+----+----+-----
 a |  1 |  1 |  1 | val

(1 rows)
cqlsh> select * from ks.t3 where c1 = 1 and c2 > 0 and c3 = 1 allow filtering;
InvalidRequest: code=2200 [Invalid query] message="PRIMARY KEY column "c3" cannot be restricted (preceding column "c2" is restricted by a non-EQ relation)"

Given that ALLOW FILTERING is required and we're querying via the index, it's probably reasonable to expect this second query to be allowed.
