gegen den Compass Server (in German) late 1998, minor updates 1999,
by Walter Hafner
Evaluation compares Compass with ht://Dig,
and PLWeb. Praises Compass for browser administration system, filtering,
virtual hosts, and realtime monitoring: downsides are proprietary database
format and price. PLWeb has some text configuration files, every efficient
customization, good indexing speed and scheduling, multiple indexes can be
created, and it is free; however it had problems with multiple servers, domains
and virtual hosts. Ht://Dig is open source and free, but can be hard to configure,
slow to index and search large indexes, and provides minimal monitoring features.
