Introduction to Hash Indexes

This is an introduction to ArangoDB's hash indexes.

It is possible to define a hash index on one or more attributes (or paths) of a document. This hash index is then used in queries to locate documents in O(1) operations. If the hash is unique, then no two documents are allowed to have the same set of attribute values.
