1. A node in a distributed indexing network in which each node has an address in an index address space and in a separate network address space, said node comprising:
- machine readable memory for storing program instructions and data structures;
one or more processors for executing program instructions stored in said memory;
program instructions stored in said memory for;
associating a subset of the index address space with the node;
maintaining a contact list, which stores the index space and network address for each of a plurality of contacts, each of which is another node in said indexing network;
treating a minority of said contact list as direct contacts and the rest of said contacts as indirect contacts;
attempting to communicate with each of the direct contacts with a minimum frequency, to determine whether or not that direct contact is still a member of the network;
responding to a determination that a given direct contact is no longer functioning as a member of the network by finding a new direct contact to replace that given contact and replacing the replaced direct contact in the node'"'"'s contact list with the index and network address of the replacement contact;
wherein the node responds to a search request for a given index address that does not fall in the subset of the index address space associated with the node by using, as the next node to send such a search request to, the address on its contact list that is closest to the given address, whether that address is a direct or indirect address;
the node learns the index address and network address of each of the node'"'"'s indirect contacts from an associated one of the node'"'"'s direct contacts; and
the node learns about changes in the state of a given indirect contact from the same direct contact from which it learned the indirect contact'"'"'s index and network address.

Abstract
Methods, apparatus, and programming recorded in machine readable memory are provided for the index, search and retrieval of objects on a global network. This inventive system embeds a distributed index in a routing layer to enable fast search. The method provides dynamic insertion, lookup, retrieval, and deletion of participating nodes, objects and associated metadata in a completely decentralized fashion. Nodes can dynamically join and leave the network. This infrastructure can be applied to content networks for publishing, searching, downloading, and streaming.
