RESTful URL design for search

Red black tree over avl tree
...times rotation O(1) can be better because it eliminates scanning remaining items O(log(n)). Because AVL tree, in average, makes more rotation, AVL tree is, usually, has better balance ~1.44 log(N) than RB-tree 2 log(N).

And if you've got a module which passes references t...
