[jira] [Comment Edited] (LUCENE-8507) TopFieldCollector should set
minimum competitive score if the primary sort is by relevancy
[ https://issues.apache.org/jira/browse/LUCENE-8507?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16620552#comment-16620552 ]

Here is a new patch that tweaks the logics a bit in order to reduce the additional conditions we need to check to set the minimum score. I ran a benchmark with luceneutil on queries sorted by field to compare with current master:
{noformat}
Report after iter 19:
TaskQPS lucene_baseline StdDevQPS lucene_candidate StdDev Pct diff
HighTermMonthSort 38.06 (9.6%) 37.53 (9.9%) -1.4% ( -19% - 19%)
HighTermDayOfYearSort 16.22 (7.0%) 16.47 (6.0%) 1.5% ( -10% - 15%)
{noformat}
