I do have a same situation. Got 30 million indexed and deleted 3 millions.
DELETE can not be posted as same way as "ADD". We can add multiple documents in the file, but not for DELETE. If there is "RANGE" of ID, make the range first then delete the record in index by {URL} <delete><query>id:[xxx TO yyy]</query></delete>. This xml should be sent to Solr engine ONE BY ONE. And I am trying to delete index directly through Lucene API. It may work, but did not try yet.

I use Solr for regular search, and it works fine for my task, but my client has a list of IDs in a flat separate file (he could have huge amount of the IDs, up to 1M) and he wants to exclude those IDs from result of the search. What is the right way to do this? Any thoughts are greatly appreciated. Thank you Gene
