>            Priority: Minor
>
> The SELECT query validation limits the predicates the custom secondary index can support.
> Possible Approaches:
> -Introduction of a special predicate string like custom_predicate which by-passes validation
> CREATE CUSTOM INDEX ON table(column)  USING 'org.example.CustomSecondaryIndex';
> Select * from table where custom_predicate=" something_only_custom_class_understands"
> This might open up possibilities like,
> - Range queries on secondary indexed columns etc
> - Wild cards
