I don't think that is possible, but you could filter the result collection and delete unwanted PageFiles links. But that is maybe not the best performance optimisation advice this year :-)

Hm, I would rather avoid filtering the whole collection afterwards, but maybe there's no other option using the SearchDataSource... :-)

Well, you can always add some timers in the code and find out actually how much time the filtering takes...

How much traffic is it on the site and how many searches are executed per hour etc,

The best thing, I guess, would be not use that pagefile folder at all, but instead create a new dedicated vpp for these douments you want to search for....

In any case, good luck :-)

Finally we've decided to create a new vpp folder for the uploads, thanx for the advice!
