	"If you are using the non-public version of Gondul, you can also perform smart searches.",
	"Distro search: Type the name of a distro-switch and all access switches registered to that distro switch will also be hilighted.",
	'Active ports: Type "active>x", "active<x" or "active=x" to identify switch with "x" amount of active gigabit ethernet (ge) ports. E.g.: "active>30".',
	'IP search: Start typing an IP and any switch with that IP registered either as management IP or part of its subnet will be identified',
	'SNMP search: Type anything found in the "sysDescr" SNMP OID to hilight a switch matching that. Practical examples include version numbers for firmware (e.g.: "JUNOS 12." vs "JUNOS 14.").'];
