Subject: Facets
General query: the client can't pick which of the supported facets to have results ordered on. I can't just ask "facet results only on subject and author, because I'll never use source"? Or is the way to do it facetLimit*dc.source=0, so you have to specify facets subtractively rather than additively? Associated with that, I assume there's the usual standard way of discovering what facets are supported by a server. 1.1.1. Facetlimit: The server decides how to truncate reported facets to meet the limit? The client may well have preferences for which 10 facets to prioritise, although presumably this is merely a matter of using facetSort, and have facetLimit return the first 10 facets according to that ordering. Still, I'd forestall the impression that the selection of facets is arbitrary. Is facetlimit*dc.subject and facetcount*dc.subject novel syntax? I'd be happier with wedging this index-specific use of facelimit as a modifier somehow into the specification of facet; the syntax looks idiosyncratic otherwise. 1.1.1.3 facetSort: No possibility of combining multiple sortBy fields, e.g. recordCount, then alphanumeric when the record count is the same? If there were more sortBy fields, there would me more point in that, of course. What does "occurrence" mean? Presence vs. absence in the index? Sorting of facets should have the flexibility of sorting in general, as supported by the Sort Context Set (among others); I assume there's no problem in using sort modifiers for facetSort as well as vanilla SortBy? 1.1.1.4.2 FacetLowValue, FacetHighValue These really should be specific to particular facets; I fear unintended results if a server attempts to apply them blanket to all facets (numbers to text, to give the obvious example). === O Roeschen Roth!
