I've noticed another compiler warning that can be easier avoided... Search\Function\CustomScoreQuery.cs(207,25): warning CS0108: 'Lucene.Net.Sear ch.Function.CustomScoreQuery.AnonymousCustomScoreProvider.reader' hides inherit ed member 'Lucene.Net.Search.Function.CustomScoreProvider.reader'. Use the new keyword if hiding was intended.
Hopefully the patch makes the problem obvious. In this particular case it doesn't cause a real problem, but I think it's worth clearing up before you tag for 2.9.2. I've also attached the batch files I use to compile. These ignore the vast majority of warning caused by the Java->C# conversion which makes spotting these potentially problematic issues more obvious. (You'll need to rename them to remove the trailing x. GMail wouldn't let be send executable files). Cheers, Andy
