Introduction
TREX is based on a client/server architecture. The client component is integrated into the application that uses the TREX functions, and allows communication with the TREX servers. The server component processes the requests; it indexes and classifies documents and answers search queries. The server component comprises of the following individual servers:
- Web server with TREX extension
- RFC server
- Queue server
- Preprocessor
- Index server
- Name server
The figure below illustrates the individual components and the communication between components:
