not unless you enforce it yourself -- there isn't anything built in to 
Solr to do this with the exception of the uniqueKey field.

There is an UpdateRequestProcessorFactory hook that you can implement to 
do arbitrary logic for each update command (regardless of wether the 
update comes from XML, CSV, or something else) ... you could add whatever 
uniqueness logic you want there.

: can't be overrided?

there is one and only one uniqueKey field ... trying to declare two should 
probably be an error 9anyone wnat to submit a patch?), but you definitley 
can't "override" the uniqueKey field ... declare it once, and that's what 
it is for your whole index.

directly in solr: no

In your own code, yes -- either in the client or in custom plugin.
