Hash indexes are fast because the exact location of the bucket is known and the hash keys are ordered sequentially. Once a key location is found, the pre-hashed value is compared to the one we’ve just found in the index to make sure it’s valid. The B-tree is a generalization of a binary search tree in that a node in a B-Tree is allowed to have more than two children. B-Tree indices help find information quickly by successively narrowing down data by assessing ranges of values stored in the node keys . A B-Tree search starts at the root node and compares the range of keys in each child node against the key value being sought. When it finds the node whose range contains the desired key value, that node is selected and then its child nodes are assessed.
