hello martijn, thx for the tip, i tried that approach but ran into two snags, 1. returning the fields makes collapsing a lot slower for results, but that might just be the nature of iterating large results. 2. it seems like only dupes of records on the first page are returned
or is tehre a a setting im missing? currently im only sending, collapse.field=brand and collapse.includeCollapseDocs.fl=num_in_stock --joe On Thu, Oct 1, 2009 at 1:14 AM, Martijn v Groningen <martijn.is.h...@gmail.com> wrote: > Hi Joe, > > Currently the patch does not do that, but you can do something else > that might help you in getting your summed stock. > > In the latest patch you can include fields of collapsed documents in > the result per distinct field value. > If your specify collapse.includeCollapseDocs.fl=num_in_stock in the > request nd lets say you collapse on brand then in the response you > will receive the following xml: > <lst name="collapsedDocs"> > <result name="brand1" numFound="48" start="0"> > <doc> > <str name="num_in_stock">2</str> > </doc> > <doc> > <str name="num_in_stock">3</str> > </doc> > ... > </result> > <result name=”brand2” numFound=”9” start=”0”> > ... > </result> > </lst> > > On the client side you can do whatever you want with this data and for > example sum it together.
