David Calavera 93d1dd8036 Make filtering a linear operation.
Improves the current filtering implementation complixity.
Currently, the best case is O(N) and worst case O(N^2) for key-value filtering.
In the new implementation, the best case is O(1) and worst case O(N), again for key-value filtering.
