Dear Mike,
On 6/21/2012 11:52 AM, Michael Kay wrote: A key can only be used to search within a single document. You can, of course, construct the union of the results of searching each individual document using the key, like this: Assuming that $allInput were bound to an arbitrary set of elements scattered across a set of documents, would there be any advantage to $allInput/root()/key('linebyfolio',$folio) ? The idea being that the documents in question could be consolidated before the call to the key function, minimizing the number of calls? Or is that likely to be taken care of for us, or unlikely to matter much?
