------------------------------------

             Summary: incorrect indexing of list collection
                 Key: CASSANDRA-8810
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8810
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: windows 8
            Reporter: 007reader
             Fix For: 2.1.2


in a table with one indexed field type list<text> data  retrieval is not working properly:

I have a simple table with an indexed list<text> field, but it shows unexpected behavior
when I query the list. Am i doing something incorrect?
 
create table test (whole text PRIMARY KEY, parts list<text>);
create index on test (parts);
insert into test (whole,parts) values('a', ['a']);      
insert into test (whole,parts) values('b', ['b']);      
insert into test (whole,parts) values('c', ['c']);      
insert into test (whole,parts) values('a.a', ['a','a']);
insert into test (whole,parts) values('a.b', ['a','b']);
insert into test (whole,parts) values('a.c', ['a','c']);
insert into test (whole,parts) values('b.a', ['b','a']);
insert into test (whole,parts) values('b.b', ['b','b']);
insert into test (whole,parts) values('b.c', ['b','c']);
insert into test (whole,parts) values('c.c', ['c','c']);
insert into test (whole,parts) values('c.b', ['c','b']);
insert into test (whole,parts) values('c.a', ['c','a']);

This is expected behavior:
------------------------------------------
select * from test where parts contains 'a' ALLOW FILTERING;

 whole | parts
-------+------------
     a |      ['a']
   b.a | ['b', 'a']
   a.c | ['a', 'c']
   a.b | ['a', 'b']
   a.a | ['a', 'a']
   c.a | ['c', 'a']

>From the following query I expect a subset of the previous query result, but it returns
no data
---------------------------------------------------
select * from test where parts contains 'a' and parts contains 'b' ALLOW FILTERING;

 whole | parts
-------+-------
