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.

Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`

Create Node Groups Using Filters or Hostname Lists

Node Groups are used for a variety of purposes in NNMi. See Create Groups of Nodes or Interfaces for more information.

Note By default NNMi Administrators can create, modify, and delete Node Groups. NNMi Administrators can configure NNMi to permit User Accounts assigned to the NNMi Operator Level 2 User Group to create, modify, and delete Node Groups.

You can create any number of Node Groups in addition to the ones that NNMi provides (see Node Groups Provided by NNMi).

One method for creating Node Groups is using filters or hostname lists to match the way your team identifies important network devices. Each Node Group is defined using one or more of the following:

Device Filters (by any combination of SNMP device category, vendor, family, profile)
Additional Filters (Boolean expressions based on a list of object attributes)
Additional Nodes (identified by case-sensitive Hostname)
Child Node Groups (use any combination of Node Groups to create a filter)

NNMi combines the results of all Node Group configuration settings in the following manner:

NNMi first evaluates Device Filters. If any exist, nodes must match at least one specification to belong to this Node Group.
NNMi then evaluates any Additional Filters. Nodes must also pass all Additional Filters specifications to belong to this Node Group.
Any Additional Nodes specified are always included in the Node Group, regardless of any filters.
Any Child Node Group results are treated the same as Additional Nodes.

Note You can also create Node Groups using the Actions → Node Group Membership option. This method adds the selected nodes to a Node Group that NNMi creates. See Create Node Groups From the Actions Menu for more information.

To create a Node Group Using Filters or Hostname Lists (if your role permits you to do this):

Navigate to the Node Group form.
1. From the workspace navigation panel, select the Configuration workspace.
2. Expand the Object Groups folder.
3. Select the Node Groups view.
4. Do one of the following:
  - To create a Node Group, click the New icon.
  - To edit a Node Group, click the Open icon in the row representing the Node Group you want to edit.
In the Node Group form, provide the required information in the Basics section.
(NNM iSPI Performance) Make the Node Group available within NNM iSPI Performance products (see NNM NNM iSPI Performance table).
Identify the nodes that belong to this Node Group.

Do one or more of the following:
- Specify a filter based on Device Profile settings using the Device Filters tab (any combination of category, vendor, family, or profile).
  
  Tip To base your filter on the SNMP system Object ID number, use the Additional Filters sysOidNode code.
- Specify a Node Group filter using the Additional Filters tab (use a variety of available codes to filter by object attribute values in the NNMi database).
- Specify individual nodes using the Additional Nodes tab (provide a list of Hostnames, as they appear in the NNMi database).
- Specify Child Node Groups using the Child Node Groups tab (use combinations of Node Groups to create a filter).
Click Save and Close to return to the Node Group form.

Note You must click Save and Close to save your changes each time you create a Node Group.
Click Save and Close.

If you configured this Node Group for Monitoring, NNMi applies your changes during the next monitoring cycle. Configure NNMi Monitoring Behavior.

You can also use the nnmloadnodegroups.ovpl command or the nnmnodegroup.ovpl command to list the following:

Names of the existing Node Groups
Selected attributes of nodes that are members of a specified Node Group

Special Actions are available for Node Groups and Interface Groups.

From the Command Line, Define Node Groups
