Re: About custom score using Solr8/Lucene8

You should think of DoubleValuesSource as a factory for DoubleValues. Usually a factory will be immutable - you set it up and then it produces per-leaf DoubleValues. So I don't really understand what you're saying about state there. Regarding the DoubleValues, which is an iterator, yes it definite

Re: About custom score using Solr8/Lucene8

Thanks Michael, if I understand correctly the DoubleValuesSource is stateful. When getValues is called if scores is null an internal state true/false is saved. This state should be returned by needsScores method. Is this correct? As far as I understood, the same thing happens to the DoubleValue ob

Re: About custom score using Solr8/Lucene8

That controls whether getValues(LeafReaderContext ctx, DoubleValues scores) gets a null scores parameter or not. You should say true only if you need the text relevance scores computed by the Query's Scorer. On Mon, Jul 6, 2020 at 10:22 AM Vincenzo D'Amore wrote: > > Hi Michael, thanks for answe

Hi Michael, thanks for answering my questions. Yes, I read, but I think that it not is enough. For make the things clearer, this is taken from the javadocs: abstract boolean needsScores() - Return true if document scores are needed to calculate values So, I thought return true, because yes, I ne

Hi all, Finally I have a custom DoubleValuesSource that gives the expected results, but I'm a little worried about the lack of documentation. When you extend DoubleValuesSource there are a number of methods to write, for some of them it is not clear what they do and why they need to be implemente
