Search for	Example	Results
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.

Search for	Operator	Example
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`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

Add Triplet Dialog Box

This dialog box enables you to define the allowed steps in a path in the topology graph leading from the source CI to the target CI when creating a subgraph definition, a compound relationship, or a calculated relationship.

To access	In Enrichment Manager, Impact Analysis Manager, or the Input Query Editor in DFM: In the Add Compound Relationship dialog box, click the Add button. For details, see Add/Edit Compound Relationship Dialog Box. In the Subgraph Definition dialog box, click Add . For details, see Subgraph Definition Dialog Box. In CI Type Manager, select Calculated Relationships from the drop-down list in the CI Types pane. In the editing pane, select the Triplets page and then click Add .
Important information	Select the query nodes and relationships to be included in the topology graph. Note The Condition fields are displayed only when you access the Add Triplet dialog box from the Subgraph Definition dialog box.

User interface elements are described below:

UI Element (A-Z)	Description
	Condition. Enables you to define attribute conditions for the source and target query nodes you selected. When the Add Triplet dialog box is opened from the Subgraph Definition dialog box, it opens the Subgraph Condition Definition dialog box. When the Add Triplet dialog box is opened from the Add Compound Relationship dialog box, it opens the Compound Relationship Condition Definition dialog box. The Condition button is enabled only after you select a query node from the Source or Target lists. Note You cannot define attribute conditions for the source and target query nodes in the CI Type Manager.
Relationship	Select an available relationship connecting the two query nodes. The list of available relationships appears only after defining both query nodes.
Relationship Direction	Select the required direction. Setting different relationship directions can achieve different query results. For an example, see Setting Different Relationship Directions for Compound Definitions. Note The Relationship list remains empty until you have selected a source and target.
Source	Select the required source query node.
Target	Select the required target query node.

Setting Different Relationship Directions for Compound Definitions

You can achieve different TQL results by setting different relationship directions. For example, in your business world, as illustrated below, you want to create a compound relationship that connects between a query node of the CIT a and a query node of the CIT b. Depth is defined at 5 (for details, see Depth).

In the Add Triplet dialog box, you can create compound definitions to link query nodes a and b using different relationship directions.

Compound Definition	Source	Target	Relationship	Relationship Direction
#1	query node a	query node c	<relationship>	source --> target
#2	query node c	query node b	<relationship>	source --> target
#3	query node c	query node b	<relationship>	source <-- target

Compound definitions 1 and 2 result in the following query:
Compound definitions 1 and 3 result in the following query:
Compound definitions 1, 2, and 3 result in the following query:
