Subject [jira] [Commented] (CONNECTORS-1066) Don't send empty fields to Solr
Date Wed, 08 Oct 2014 14:18:34 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1066?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14163536#comment-14163536

Shinichiro Abe commented on CONNECTORS-1066:
--------------------------------------------

Because the sort order in a repository and the order in search engine will not match. For
example, database column (jdbc connector) order and Solr sort field order. 
Also, Alfresco can have the properties which can have a blank, right? I customized cmis connector
which crawled to Alfresco before, at that time I have to send a blank(currently cmis connector
ignores empty string but I tweaked this) to Solr because the user wanted to look at present
fields regardless of a blank or non blank. And the user wanted to sort by a present field
because he didn't like the order which got changed by missing field.
IMO, in repository connector we have to control whether blank or not when putting RepositoryDocument.
I can understand it is easy to control blank or null at HttpPoster, but it's not a proper
place.
