[jira] [Commented] (LUCENE-7386) Flatten nested disjunctions

    [ https://issues.apache.org/jira/browse/LUCENE-7386?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16813211#comment-16813211 ] 

Adrien Grand commented on LUCENE-7386:
--------------------------------------

For the record I had to disable the verification of scores for this run of the benchmark since this change removes intermediate casts to float which trigger slight changes in the produced scores.

> Now that coords are gone it became easier to flatten nested disjunctions. It might sound weird to write nested disjunctions in the first place, but disjunctions can be created implicitly by other queries such as more-like-this, LatLonPoint.newBoxQuery, non-scoring synonym queries, etc.
