Apart from that great so far... was (Author: dredford): There is an issue with collapsed result ordering when querying with only the unique Id and score fields in the request. eg: q=ford&version=2.2&start=0&rows=10&indent=on&fl=Id,score&collapse.field=PrimaryId&collapse.max=1 gives wrong order (note: Id is our unique Id) but q=ford&version=2.2&start=0&rows=10&indent=on&fl=Id,score,bogus&collapse.field=PrimaryId&collapse.max=1 Also using an fq make it work eg: fq=Type:articles&q=ford&version=2.2&start=0&rows=10&indent=on&fl=Id,score&collapse.field=PrimaryId&collapse.max=1 I'm using the latest Dmitry patch (25/mar/09) against 1.3.0.
