Subject Re: About custom score using Solr8/Lucene8
Date Thu, 09 May 2019 07:13:12 GMT
Hello Mikhail,
yes i did. I read all the page at https://issues.apache.org/jira/browse/LUCENE-8099 <https://issues.apache.org/jira/browse/LUCENE-8099>

I still do not understand where/how to start to write a class to be embedded in solr8. All
available example since 2012 where written around CustomScoreQuery/CustomScoreProvider.

I really don’t know how to setup a minimal project to implement custom scoring in solr8/lucene8
using FunctionScoreQuery
