When we say "reindex", we mean, literally, +"index it again". However you got the data into the index the first time, you will run that process again. Review comment: [0] It's implied in everything you have here, but I would make the point a little more explicit if you added a sentence at the end of this paragraph like: "It is strongly recommended that Solr users index their data in a repeatable, consistent way, so that the process can be easily repeated if the need for indexing arises" ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
