> LogSearch deletes logs older than 7 days (by default). The indexed documents doesn't get purged until the segments are merged. Currently the mergeFactor is 25, which is pretty large. If documents are not purged, then the indexes occupy disk and memory. 
> It is better to make the mergeFactor value to be 5 and let Solr purge deleted documents more regularly.
> The following 2 files needs to be updated:
> ambari-server/src/main/resources/common-services/LOGSEARCH/0.5.0/properties/audit_logs-solrconfig.xml.j2
> ambari-server/src/main/resources/common-services/LOGSEARCH/0.5.0/properties/service_logs-solrconfig.xml.j2
