By connecting to port 80 (or 443, if you want HTTPS) on logsene-receiver.sematext.com / logsene-receiver-syslog.eu.sematext.com (if using Sematext Cloud Europe), you can use the Elasticsearch API to search through your data, in the same way you can send it.
Besides web UI, there's also Logsene CLI, a command line
interface for searching through logs, with the ability to pipe the
sort and other useful shell commands.
See Logsene CLI Introduction.
