Turtle & J. Flood, that I find deserves more attention among Lucene users (and developers). > I implemented a proof of concept and did some performance measurements with example queries and lucenebench, the package of Mike McCandless, resulting in very significant speedups. > This ticket is to get started the discussion on including the implementation into Lucene's codebase. Because the technique requires awareness about it from the Lucene user/developer, it seems best to become a contrib/module package so that it consciously can be chosen to be used. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@lucene.apache.org For additional commands, e-mail: dev-help@lucene.apache.org
