------------------------------------
Summary: Remove trackDocScores from TopFieldCollector factory
methods
Key: LUCENE-8412
URL: https://issues.apache.org/jira/browse/LUCENE-8412
Project: Lucene - Core
Issue Type: Task
Reporter: Adrien Grand
Computing scores on top hits is fine, but the current way it is implemented -
at collection time - requires to read/decode more freqs/norms and compute more
scores than necessary. It would be more efficient to compute scores of top hits
as a post-collection step by only advancing the scorer to hits that made the
top-N list.
