Abstract: Methods, systems, devices and computer program code products for enabling searches of digital communications network traffic to identify information transmitted by, received by, or exchanged with a given human or non-human entity, include, or include elements for, translating Pcap 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 text-based searches 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 file or IP network packet data.
