Just asked the same question on the hector-dev group a few minutes ago. Seems indeed to be the case that cassandra only uses 1 index. At least this would make sense narrowing down issues I have that get foo where col1=cond1 and col2=cond2 works while flipping conditions get foo where col2=cond2 and col1=cond1 returns no results no more. Unfortunately nobody around here seems to care...
