             Summary: Reconsider the best way to encode postings now that we can skip non-competitive hits
                 Key: LUCENE-8760
                 URL: https://issues.apache.org/jira/browse/LUCENE-8760
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand


The fact that we now skip non competitive hits has some implications to our postings:
 - we are now more likely to call advance vs. nextDoc
 - we are less likely to read term frequency for a given doc, since we only do that if the maximum score reported by impacts is competitive
 - we are less likely to read positions for a given doc, since exact phrase queries first check the maximum score that would be obtained with a phrase freq equal to the minimum of all term freqs

It might be a good opportunity to re-explore the best way to encode postings.
