: But if I update an existing document, and I don't pass in a value for the : booleen field, will Solr keep the existing booleen value unchanged, or will : it update the booleen value again using the default? - ie. true.
Updating a document is very simplistic -- it removes the old one (by id) and then adds the new version -- it will have no "memory" of values from the old version of the document. -Hoss
