An interesting issue we have found with a solution with a large number of language enabled and pages localised in these languages, the automatic indexing events work fine for creating, updating and deleting content however we have found that when you use the language labs gadget to delete the content language version that the find content item for that langauge still exists in the index.

Is there a find indexing event to remove a content item from the index if you delete the content item för a specific langauge?
