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)`

A Usage Example

This example demonstrates how to make a POST call to execute a TQL query by definition to return the name of all CPUs of which the attribute contains Pentium.

Step 1. Retrieve the authentication token

To do this, make a POST call to https://localhost:8443/rest-api/authenticate with the following payload:

{
"username": "sysadmin",
"password": "Sysadmin?123", 
"clientContext": 1
}

Note This example assumes that the REST API is deployed at the following location:

https://localhost:8443/rest-api

You then receive a response that resembles the following:

Status: 200
Response body:
{
 "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE0NzQzNTc3MDYsImN1c3RvbWVyIjoxLCJ1c2VybmFtZSI6InN5c2FkbWluIn0.cVYsuum1CqaqfZV1K5KJ8nidOOif8Wv9tZsLFFZPbSs"
}

Step 2. Make a POST call to run the TQL query

Make a POST call to https://localhost:8443/rest-api/topologyQuery with the following payload:

{
   "nodes":  [
     {
       "type": "cpu",
       "queryIdentifier": "cpu1",
       "visible": true,
       "includeSubtypes": true,
       "layout": ["name"],
       "attributeConditions": [{
          "attribute": "name",
         "operator": "like",
         "value": "%Pentium%"
     }],
     "linkConditions": []
  }],
 "relations": []
}

At the same time you need to set the following header:

Authorization Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE0NzQzNTc3MDYsImN1c3RvbWVyIjoxLCJ1c2VybmFtZSI6InN5c2FkbWluIn0.cVYsuum1CqaqfZV1K5KJ8nidOOif8Wv9tZsLFFZPbSs

Note The payload specifies the layout attribute to name, so that the CPU name will be returned.
