1. A method for enabling a search of digital communications network traffic to identify information transmitted by, received by, or exchanged with a given human or non-human entity via the digital communications network, the method comprising: translating Pcap (packet capture) files or streams of IP network packets obtained from the network into a scalable form suitable for query by search engine functionality, thereby to enable scalable, text-based search of network information contained in the Pcap files, and providing scalable search engine functionality to enable a user to execute a text-based search on textual or human relationship-identifying information derived from the Pcap files or streams of IP network packets, thereby to identify information transmitted by, received by, or exchanged with the given human or non-human entity, wherein the scalable search engine functionality is capable of scaling to search massive quantities of Pcap files or IP network packet data.
