ed7e02cfa32ad8e48738ba9643952e792ff5dc7f Introduced a new `raw_filter` param, which allows passing in a raw filter string. This is basically a lazy way of allowing complex filtering that the package doesn't support, such as OR-ing multiple filters together. Also added some more bracketing to the filter expression that gets built, as there were some edge cases where ORs and ANDs were not binding in the proper order.
