Administration of Search and Classification (TREX)

Prerequisites

TREX offers a flexible architecture that enables a distributed installation that is modified to different requirements. A minimal system consists of a single host that provides all TREX functions. Starting with a single-host system, you can extend TREX to be a distributed system and thus increase its capacity.
