How do a create an iPhoto Smart Album of ANY of the names X, Y or Z but only for the year 2013
It's not possible with iPhoto smart albums because you can't combine a conjunction with a disjunction in the same smart folder.  This would work, in a convoluted way, if iPhoto let you use a smart folder as an input, but unfortunately it doesn't (i.e., Album is MY_SMART_XYZ_ALBUM AND date is 2013).  iTunes can do this, but apparently not iPhoto.  Theoretically, it's possible to create "dumb" albums with smart contents in Automator, though.  It should also be possible to filter a conjunctive set of elements with a subsequent disjunctive criterion.  But I'm not sure how fast this would perform.
