Hello all, Short version: I'm about to remove the FSTOrd postings format.
Longer version: I'm trying to simplify the API we have for the terms dictionary to interact with postings. This involves removing an API that is only used by the FST and FSTOrd postings format, as a way to store intermediate outputs on intermediate arcs of the FST that serves as a terms dictionary. The FST postings format is preserved but its behavior is changed since it now only stores outputs on final arcs. However the FSTOrd postings format is removed by this change. More information at https://issues.apache.org/jira/browse/LUCENE-9116 and https://github.com/apache/lucene-solr/pull/1158. -- Adrien
