Subject [jira] [Commented] (OAK-2399) Custom scorer for modifying score per documents
Date Tue, 24 Mar 2015 15:43:53 GMT

    [ https://issues.apache.org/jira/browse/OAK-2399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14378041#comment-14378041
] 

Rishabh Maurya commented on OAK-2399:
-------------------------------------

Following points needs to be considered - 
1. Only ordered properties are stored as DocValues, so if scorer requires reading DocValues
for a field, then its property definition must be set as ordered. So we can have a enhancement
to configure field type as DocValues as a part of property definition.

2. DocValue field names are prefixed with {{:dv}}, [~chetanm] suggested to expose [FieldNames.java|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-lucene/src/main/java/org/apache/jackrabbit/oak/plugins/index/lucene/FieldNames.java],
as naming convention is implementation detail.
