A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Island Node Groups

An Island Group is a group of fully-connected nodes discovered by NNMi, and NNMi determines this group is not connected to the rest of the topology.

An example of an environment with multiple Island Node Groups is a financial institution or retail store with many branches or stores. Each branch or store might be connected to other branches or stores with a WAN (Wide Area Network) connection. Each branch or store appears as an isolated island of nodes in the NNMi topology.

NNMi automatically updates Island Node Group discovery information whenever it detects changes in Layer 2 Connections. NNMi begins rediscovery of the Island Node Group within a range of 10 seconds to 10 minutes, depending on current network traffic volume. NNMi uses the Discovery Interval to determine when the updates occur.

Note the following about Island Node Groups:

NNMi selects a representative node in each Island Node Group as the Source Node associated with an Island Node Group incident. The representative node is selected using the following criteria:
- Sort all routers in the Node Group alphabetically by name and choose the first one in the list
- If no routers are in the Node Group, sort all nodes in the Node Group alphabetically by name and choose the first one in the list.
Island Node Groups are identified using "Island" in the Node Group Name. NNMi also assigns each Island Node Group name a number to ensure the name is unique.
Island Node Groups are manage internally. Therefore, NNMi administrators should not modify Island Node Group configurations. NNMi overrides any user changes the next time NNMi updates the Island Node Group discovery information.
Island Node Groups must have at least two nodes.
How the Status of Island Node Groups is calculated cannot be changed.

The only possible Status values for Island Node Groups are Unknown and Normal. Unknown indicates that NNMi cannot reach any nodes in the group. Normal indicates that NNMi can reach at least one node in the group.
