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.

Discovery Seeds for Auto-Discovery in Default Tenant

Discovery seeds are optional for the Nodes in the Default Tenant, but required for each Node assigned to any other Tenant.

Caution If your network uses any of the following IPv4 translation protocols, you must create a unique Tenant (other than Default Tenant) for each domain of nodes with addresses determined by the following protocols (see Overlapping Addresses in NAT Environments):

Static Network Address Translation (NAT)
Dynamic Network Address Translation (NAT)
Dynamic Port Address Translation (PAT/NAPT)

A discovery seed is a specific node that you want NNMi to discover. For example, a discovery seed might be a core router in your management environment.

Each discovery seed is identified by hostname (not case-sensitive) or IP address, and Initial Discovery Tenant assignment. When you add a discovery seed, NNMi immediately tries to discover that device (without waiting until the next regularly scheduled discovery interval). If discovery is not successful, NNMi tries again 10 minutes later, and continues trying. The time between each attempt is doubled until the time reaches 1 week or equals your current discovery interval.

NNMi discovers seed addresses regardless of how you configure Auto-Discovery Rule definitions or the Excluded IP Addresses filter.

Note Nodes configured as discovery seeds are always discovered and added to the topology database. If you change your mind and delete a discovery seed configuration, the node is not automatically deleted from the topology database. See Delete Nodes.

If you configure one or more Auto-Discovery Rules, note the following:

If Discover Matching Nodes is enabled for an Auto-Discovery Rule, NNMi uses each discovery seed as a starting point to gather information about neighboring devices to expand discovery.

Note You can use the Ping Sweep option in your Auto-Discovery Rules in addition to or instead of Discovery Seeds.
If Discover Matching Nodes is disabled for an Auto-Discovery Rule, no devices matching that rule's criteria are discovered and added to the topology database unless:
- The device's address is a discovery seed.
  
  See Specify discovery seeds to learn how to establish discovery seeds.
- The device's address is reported as a neighbor to another discovered address.
  
  If you want to ensure that an address is never added to the NNMi database, use the settings for Configure an Excluded IP Addresses filter or Configure an Excluded Interfaces filter.
