I'm new to ES. We're test-piloting ELK 4 for webstats. How do I get _rid_ of ratty data? Like this: I've got my 8 apache web servers sending access logs, I've got the log format looking good, GEOIP setup. I even have some basic stats on the Kibana Dashboard. I've had this running for six days or so. I have even figured out that my servers were logging a ton of messages about their healthcheck, which was dirtying the stats, and have setup logstash to remove those. But _now_ I have a week, or so, of data that isn't right. I can explain, when I turn this over to the end user, that data from June 1 - June 6 is bad, pay no attention, but I'd prefer to work some magic and have ES take them away. Is there an incantation for that? A doc I can read? ---

Do you need the indices still? I mean, is there other data in there that you still need? **Yes:** A delete\_by\_query to delete everything of type "apache" (presuming you used Logstash to type individual inputs). **No:** Use [Elasticsearch Curator](https://www.elastic.co/guide/en/elasticsearch/client/curator/current/index.html) to delete indices older than _n_ days. ---

It's tempting to discard 'all' and start over again - I'll think about both. ---
