You're going to have to be very specific about what you want Solr to do. > The other(kinda better) way to do it, is to set a collection-level > ttl, and when indexes are merged, they will drop the documents that > have expired in the new merged segment.

Does the following describe the the feature you're after? https://lucidworks.com/blog/2014/05/07/document-expiration/ If this is what you're after, this is *Solr* functionality. Segment merging is *Lucene* functionality. Lucene cannot remove documents during merge until they have been deleted. It is Solr that handles deleting documents after they expire. Lucene is not aware of the expiration concept. > 2. is there a way to support this also on get ? looks like I can use > realtimeget + filter query and it should work based on documentation Realtime get allows you to retrieve documents that have been indexed but not yet committed. I doubt that deleted documents or document expiration affects RTG at all. We would need to know exactly what you want to get working here before we can say whether or not you're right when you say "it should work." Thanks, Shawn
