You should be able to cache the results of the Xindice query by 
extending org.apache.cocoon.components.source.XMLDBSource and overriding 
getLastModifiedTime() to return something different from zero.

It would be nice if Xindice provided the modification time of a 
collection, you could use it as a value to return from 
getLastModifiedTime(). Unfortunately it does not, so you'll have to 
resort to application-specific methods.

P.S.: I've taken the liberty to CC xindice-dev.
