Noble Paul commented on SOLR-5795:
----------------------------------

[~upayavira] There already is a field in the doc which marks the expiry time. 
So the same field can be used right? An option to not delete the docs (don't 
run the scheduler) . But at query time you should be able to retrieve the 
deleted docs with an extra filter/flag 

> Option to periodically delete docs based on an expiration field -- or ttl 
> specified when indexed.

> A question I get periodically from people is how to automatically remove 
> documents from a collection at a certain time (or after a certain amount of 
> time).  
> Excluding from search results using a filter query on a date field is 
> trivial, but you still have to periodically send a deleteByQuery to clean up 
> those older "expired" documents.  And in the case where you want all 
> documents to auto-expire some fixed amount of time when they were indexed, 
> you still have to setup a simple UpdateProcessorto set that expiration date.  
> So i've been thinking it would be nice if there was a simple way to configure 
> solr to do it all for you.
