Subject [jira] [Updated] (SOLR-5795) Option to periodically delete docs based on an expiration field -- or ttl specified when indexed.
Date Sat, 29 Mar 2014 00:11:21 GMT

Hoss Man updated SOLR-5795:

bq. that said: having a sensible default probably would make the common case more useful –
and we could always document (and test) using {{<null name="ttlFieldName"/>}} for people
who wnat to disable it.

Updated patch adds support for {{\_ttl\_}} as a default for both {{ttlFieldName}} and {{ttlParamName}}.

> 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.
