Subject [jira] [Commented] (SOLR-9822) Improve faceting performance with FieldCache
Date Sun, 04 Dec 2016 14:42:59 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15720050#comment-15720050
] 

Yonik Seeley commented on SOLR-9822:
------------------------------------

bq.  the lambda leads with if (ord >= 0) but why would it ever be less? 

The code before the iterator switch-over had the same check since getOrd(doc) returned -1
for "missing".
For iterator style, ordValue() will never return -1 anymore, so the branch will be predictable
in that case.
