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.

Node Name Resolution

By default, NNMi attempts to identify a node in the following order:

Short DNS name
Short sysName
IP Address

Note If you change a node's hostname, there is a delay before NNMi data reflects the name change, because NNMi caches DNS names to enhance performance.

The following scenarios describe situations in which you might want to change the default order for node name resolution:

If your organization is dependent on others to update the DNS configuration, you might set a policy of defining the sysName for each new device as it is added to the network. In this case, set select sysName as the first choice for node name resolution so that NNMi can discover the new device as soon as it is deployed in the network. (Maintain the sysName over the life of the device.)
If your organization does not set or maintain the sysName for managed devices, select sysName as the third option for node name resolution.

Tip: If you use the full or short DNS name as the primary naming convention, confirm that you have forward and reverse DNS resolution from the NNMi management server to all managed devices.

Note When the full DNS name is the naming convention, labels on the topology maps can be long.

Tip: NNMi selects the lowest loopback address as the management address for Cisco devices, so put DNS resolution on the lowest loopback address for each Cisco device.
