: A followup. The wiki has a whole discussion of the 'update' XML : message. But solrj has nothing like it. Does that really exist? Is : there a reason to use it? If I just 'add' the document a second time, : it will replace?
You should only see "update" in Solr docs used in the context of "updating" the index by adding (which might be replacing) or deleting documents. (you'll note there is no "<update>" tag or anything like that in the XML syntax) -Hoss
