You should reuse as much as possible the Work infrastructure. Probably adding a new WorkType.PURGE Pretty much how WorkType.INDEX is done, I guess There is 2 types of purge however, purge by class and id, ie purge a given document, or purge the whole index(es) by class. I also mentionned thw Workspace class, but I don't thing there is a need to access it directly from the session. Following the Work path up to the LuceneWorker and the Workspace should do it.
