Mistake at line 107 of SearchParser.java:
if (c.equals("m") || c .equals("s") || c.equals("h"))
I hope it needs to look like:
if (c.equals("m") || c .equals("s") || c.equals("h") || c.equals("d") || c.equals("w"))

Not working ingame command example:
/hawk rollback p:Player1 t:2d

Fixed by this commit.
