Thanks for the response Erick. I’m deleting the documents with expungeDeletes
option set as true. So, that does trigger a merge to throw away the deleted
documents.

Not sure what you're really looking for here. Size on disk is _never_
reduced by a delete operation, the document is only 'marked as
deleted'. Only when segments are merged are the resources reclaimed,
i.e. the index gets smaller. You can figure out what % of your index
consists of deleted documents by the delta between numDocs and
maxDocs, available on the admin UI and from the Luke handler (and
maybe JMX).
Best,
Erick
