Can the Locator find, say, only large print editions of a title?
At this point, the main reason the Locator cannot do this is the Z39.50 client software used by SILO; when new versions of the software are out it will be possible to do this kind of sort. HOWEVER, that is only one factor; the other major factor is the cataloging of the records that are read and manipulated by the software. It will look in particular places for codes for such things as large print and, if the cataloger has not put that code in the correct place, the Locator will still not be able to use it.
