As long as you don't have any commits with openSearcher=true happening between the delete and the insert, that would work ... but why go through the manual delete if you don't have to? If you define a suitable uniqueKey field in your schema, simply indexing a new document with the same value in the uniqueKeyfield as an existing document will delete the old document. https://wiki.apache.org/solr/UniqueKey Thanks, Shawn
