Not sure if it is what you are after, but it is essentially multivalued FC. Sorting on multivalued is definitely a subjective matter that a function query would rock in, having an FC or VS that supports is would make that much easier, like say events where an event can have multiple dates, sort_date_compared(performance_dates, NOW) I suppose if you have a multivalued function (see the Vector Distance stuff), you can do that already. This is in fact how sort by distance works on trunk now. Or even distances from a poly, polyDistance(convexHull, point) or polyDistance(center, point) etc.. Yep.

Yeah, not that much is public in UnInvertedField- On Fri, Feb 19, 2010 at 6:56 AM, Grant Ingersoll gsing...@apache.orgwrote: On Feb 18, 2010, at 1:54 PM, patrick o'leary wrote: Cool, we want to examine certain fields of a docset which currently is a multivalued field, obviously only the first value gets loaded into field cache.

Re: poly fields in fieldcache
For sorting or just in general? Sorting currently is not supported for PointType, etc. (although it probably could be if someone wanted to define it, although I'm not a 100% sure what it would mean in all cases). In reality, Poly Fields are just semantic sugar around other fields, at least that is how the current ones are implemented. So, I suppose they could be made to work w/ the field cache, if they don't already. I'd have to look specifically, but they do support loading via a ValueSource. Is there something specific you are looking to do? -Grant On Feb 17, 2010, at 6:12 PM, patrick o'leary wrote: Quick question: Can poly fields be accessed through fieldCache ?
