Abstract
In one embodiment, a method comprises identifying prefix groups for searchable character symbols, each prefix group having a corresponding searchable character symbol comprising at least one searchable character; assigning at least one prefix group to each of a plurality of distributed hash table nodes in a network, each distributed hash table node containing at least one of the prefix groups, each distributed hash table node assigned a corresponding prescribed keyspace range of a prescribed keyspace, each distributed hash table node configured for storing data records having respective primary data record keys within the corresponding prescribed keyspace range; and assigning secondary indexes that start with one of the searchable character symbols to the corresponding prefix group in the associated distributed hash table node, enabling any prefix search starting with the one searchable character symbol to be directed to the corresponding prefix group in the associated distributed hash table node.
