It is natural part of the update model for Solr (and for many other search engines). Solr does not do updates. It does add, replace, and delete.
Every document is processed as if it was new. If there is already a document with that id, then the new document replaces it. The existing documents are not read during indexing. This allows indexing to be much faster than in a relational database. wunder On Feb 16, 2013, at 8:40 PM, Isaac Hebsh wrote: > The component who sends the document does not know whether it is a new > document or an update.
