I can think of two quick possibilities: 1> Just do a delete by query via XML, something like <delete><query>specfield:value</query></delete>. You could use curl or put it on the http request (separate from the delta import). There's an example of posting via post.jar here: http://lucene.apache.org/solr/tutorial.html curl example: curl http://localhost:8983/solr/update -F stream.body='your query here'
2> WARNING: I haven't had occasion to use this, but did you look at preImportDeleteQuery?
