appears you are targeting 9.0 for your code lucene/core/src/java/org/apache/lucene/codecs/lucene90/Lucene90FieldInfosFormat.java<https://github.com/dashbase/lucene-solr/pull/1/files#diff-224246aa19a54dd91fc495a6bbf7d75b26dbeaa3aceab058214d68fcbb38d24c> (Lucene90FIeldInfosFormat.java is not contained in either 8.4 or 8.7 distros)
<RANT> someone had the bright idea to nuke ant 8.x build.xml without consulting anyone not a fan of ant but the execution model of gradle is woefully inflexible in comparison to maven </RANT> i will try with 90 distro to get the codecs/lucene90/Lucene90FieldInfosFormat and recompile and hopefully your TestLucene84PostingsFormat will run w/o fail or error Thx martin- ________________________________ From: John Wang <john.w...@gmail.com> Sent: Wednesday, January 6, 2021 10:15 AM To: dev@lucene.apache.org <dev@lucene.apache.org> Subject: Re: additional term meta data Hey Martin: There is a test case in the PR we created on our own fork: https://github.com/dashbase/lucene-solr/pull/1, which also contains some example code on how to access in the PR description. Here is the link to the beginning of the tests: https://github.com/dashbase/lucene-solr/blob/posting-last-docid/lucene/core/src/test/org/apache/lucene/codecs/lucene84/TestLucene84PostingsFormat.java#L142 I am not sure which version this should be applied to, currently, it was based on master as of a few days ago. We intend to patch 8.7 for our own environment. Any advice or feedback is much appreciated. Thank you! -John On Wed, Jan 6, 2021 at 3:28 AM Martin Gainty <mgai...@hotmail.com<mailto:mgai...@hotmail.com>> wrote: how to access first and last? which version will you be merging ________________________________ From: John Wang <john.w...@gmail.com<mailto:john.w...@gmail.com>> Sent: Tuesday, January 5, 2021 8:19 PM To: dev@lucene.apache.org<mailto:dev@lucene.apache.org> <dev@lucene.apache.org<mailto:dev@lucene.apache.org>> Subject: additional term meta data Hi folks: We like to propose a feature to add additional per-term metadata to the term diction. Currently, the TermsEnum API returns docFreq as its only meta-data. We needed a way to quickly get the first and last doc id in the postings without having to scan through the entire postings list. We have created a PR on our own fork and we would like to contribute this back to the community. Please let us know if this is something that's useful and/or fits Lucene's roadmap, we would be happy to submit a patch. https://github.com/dashbase/lucene-solr/pull/1 Thank you -John
