indexer.conf
Robots defines which robot directives should be respected when crawling:
robotstxt - respect the Robots exclusion standard (robots.txt files).
xrobotstag - respect the X-Robots-Tag HTTP header.
meta - respect HTML robots meta tags, e.g.:
rel - respect the rel attributes in HTML links, e.g.:
yes - respect all robot directives.
no - ignore all robot directives.
Setting Robots to no can be useful when running mnoGoSearch for site validation purposes, as well as when crawling your own Web site.
The default value is yes, for polite crawling purposes.
Robots can be used multiple times and affects on all following Server and Realm commands until the end of the configuration file, or until the next Robots command.
