Shinichiro Abe commented on CONNECTORS-1066:
--------------------------------------------
Solr DIH ignores null but does not ignore blank unless we don't use
Transformers or RemoveBlankFieldUpdateProcessor.
http://svn.apache.org/viewvc/lucene/dev/branches/lucene_solr_4_10/solr/contrib/dataimporthandler/src/java/org/apache/solr/handler/dataimport/DocBuilder.java?view=markup#l675
By above spec, I thought blank treatment was responsible for a user(i.e modify
SQL or add custom Transformer for blank), so I said "It is wrong to put blank
to RepositoryDocument in repository connector". I don't mind to make the
checkbox default to being checked if this is a new MCF 2.0 feature.
