Ability to create $or queries

[pajtai]

Currently adding multiple key, comp, value triplets does an and. Should be able to pass an option to make it an or.

As part of this and / or update should also specify in docs whether you are doing ands or ors when you do multiple keys or multiple values.

What would the expected priority be? Seems like it would have to be all AND or all OR since we don't want to overly complicate the querying of data.

Maybe an orFilters key that can only be used if you have no filters key. Syntax wise that's simpler than some sort of filters: {or:[...]}
