Hi Walter; I am new to Solr and digging into code to understand it. I think that when indexer copies indexes, before the commit it is unsearchable.
Where exactly that commit occurs at code and can I say that: rollback something because I don't want that indexes (reason maybe anything else, maybe I will decline some indexes(index filtering) because of the documents they points. Is it possible? 2013/4/7 Walter Underwood <wun...@wunderwood.org> > This is precisely how Solr replication works.
