Tuning search server cache settings

Question

In search cluster manager under WCI Administration utilities in WCI Portal console, we see a warning msgs as below:
-Docset cache size used does not match the recommended size for this configuration
-Index cache size used does not match the recommended size for this confguration
How to tune the search server cache settings?

Answer 1

Actually, I think these configurations should be done (in WCI 6.5 or higher) in the configuration.xml located in /alui/settings.
