Overview

There are two types of Oracle Database Server discoveries:

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)`

The general Oracle Database Server discovery, which discovers all the Oracle Database Servers on the network. There are two methods available:

Thorough Discovery. This is a comprehensive discovery method that uses Node CI as an input trigger CIT. For information on this type of discovery, see How to Discover Oracle Database Servers by SQL.

Lightweight Discovery. This is a lightweight method of discovery that uses IPServiceEndpoint as an input trigger CIT. For information on this type of discovery, see How to Discover Oracle Database Servers- Lightweight.

Oracle TNS Names Topology discovery, which discovers all the Oracle Database Servers that are stored in the Active Directory using the LDAP protocol. For more information on this type of discovery, see How to Discover Oracle TNS Names Topology.
