> Since C* 2.1 we're able to index map keys or map values and query them using {{CONTAINS KEY}} and {{CONTAINS}} respectively.
> However, some use cases require being able to filter for specific key/value combination. Syntax might be something along the lines of 
> {code:sql}
> SELECT * FROM table WHERE map['country'] = 'usa';
> {code}
> or
> {code:sql}
> SELECT * FROM table WHERE map CONTAINS ENTRY { 'country': 'usa' };
> {code}
> Of course, right now we can have the client refine the results from
> {code:sql}
> SELECT * FROM table WHERE map CONTAINS { 'usa' };
> {code}
> or
> {code:sql}
> SELECT * FROM table WHERE map CONTAINS KEY { 'country' };
> {code}
> but I believe this would add a good deal of flexibility.
