Components of a QQL query

AND

Returns query results that include all the free-text values and values with the restricted searches that you combine with the AND operator in your query.

For example, to find the assets with both the Shellshock vulnerability and the Heartbleed vulnerability, form the following query:

vulnerabilities.vulnerability.title: shellshock AND vulnerabilities.vulnerability.title: heartbleed

NOT

Returns query results that don't include the free-text values or values with restricted search that you combine with the NOT operator in your query. So, when you use the NOT operator, you are telling the database to exclude the value that follows the NOT operator from search.

For example, to exclude assets from Passive Sensor, you form the following query:

not inventory.source: `Passive Sensor`

Note: We recommend that you reduce, or eliminate, the use of the NOT operator in a query. So, to exclude vulnerabilities of the type “Information Gathered” from search, form the following query instead:

vulnerabilities.typedetected:[CONFIRMED, POTENTIAL]

OR

Returns query results that include one or more of the free-text values or values with search restrictors that you conditionalize with the OR operator in your query.

For example, to find vulnerabilities from Rockwell automation or Omron, form the following query:

vulnerabilities.hardware.vendor: "Rockwell Automation" or vulnerabilities.hardware.vendor:"Omron"

Note: It’s a good practice to use double-quote characters around your character string values, especially those that contain blank space.

:

A colon (:) separates a query search token from token value. After the colon, you can use various search restrictors with the token value and conditionalize your search query to get the most relevant results.

=

Returns results where the property value stored in the database is equal to the search token value that you specify in your query. You must use the = operator with the < or the > operator. For example, if you build a query vulnerabilities.severity>4, you get all the results that have the vulnerability severity 5. But if you build a query vulnerabilities.severity>=4, the results are of both severity 4 and 5. We don't recommend using the = independently. Use the : operator instead.

<

Returns all the results where the property value stored in the database is less than the search token value that you specify in your query. You must replace the : operator after the token with <.

For example, to find out vulnerabilities that are older than last 30 days, form a query as vulnerabilities.lastFound<now-30d.

>

Returns all the results where the property value stored in the database is greater than the search token value that you specify in your query. You must replace the : operator after the token with >.

For example, to find out vulnerabilities that were detected in the last 30 days, form a query as vulnerabilities.lastFound>now-30d.

<=

Returns all the results that have the stored values less than or equal to the search token value that you specify in your query. You must replace the : operator after the token with <=.

For example, to find out vulnerabilities that were first detected on or before May 21, 2020, for a query as vulnerabilities.firstFound<=2020-05-21

>=

Returns all the results that have the stored values greater than or equal to the search token value that you specify in your query. You must replace the : operator after the token with >=.

For example, to find out vulnerabilities that were first detected on or after May 21, 2020, for a query as vulnerabilities.firstFound>=2020-05-21 .

..

Returns the results where the token value falls within the range that you specify. Ranges can be specified with the [lower .. upper] syntax using parentheses and brackets.

This is supported for numeric and date fields.

See Range Searches

*

When you use the wildcard operator (*) with a part of a word in your query value, you get the results based on the exact matches.

If you type a part of a word followed by the wildcard operator, you enable the prefix matching.

For example,

vulnerabilities.hardware.vendor: Rock*  will return the vulnerabilities from Rockwell

vulnerabilities.hardware.type: Communication*  will return the vulnerabilities from communication module

If you use the wildcard operator followed a part of a word, you enable the suffix matching.

For example,

hardware.category1:*Instruments

`<value>`

Returns all the results that contain the exact value string that you enclose in the grave accent marks (also called backticks) in your query.

You can also look for case-sensitive matches by using backticks.

For example,

To find out the asset with the name “ACMENVT7,” form the following query:

asset.name: `ACMENVT7`

“<value string>”

Returns all the results that contain the value string that you enclose in the double quotation marks in your query.

For example,

To list the vulnerabilities that contain “Remote” or “Code” or both in their title, form the following query:

vulnerabilities.vulnerability.title: “Remote Code”

[…]

Square brackets are typically used in range searches such as date ranges or IP address ranges. If you use brackets, the result includes all the values that fall between the lower limit value and the upper limit value in the range including both these values.

For example, to find out the open ports in your asset inventory, you create the following query:

openPorts.port: [123 .. 1234]

In this case, the result returns all the values that are greater than or equal to 123 and less than or equal to 1234.

(..)

Round brackets (parentheses) are also used in range searches.  the result includes all the values that fall between the lower limit value and the upper limit value in the range excluding both these values.

For example, to find out the open ports in your asset inventory, you create the following query:

openPorts.port:(123 .. 1234)

In this case, the result returns all the values that are greater than but not equal to 123 and less than but not equal to 1234.
