Simple and Complex Search Query Examples

This article contains a number of example searches, based on Cisco Vulnerability Management supported search terms.

To use any example, copy the entire search string from a cell in one of the tables below and paste it into the "CUSTOM QUERY STRING" text bar located below the Risk Meter on your Explore page.

Advanced Search Notes

Advanced Search Notes

  • Logical operators must be in complete uppercase. For example:
    • AND, OR are valid.
    • And, and, Or, or are not valid.
  • The AND operator means that an item must match both conditions for results to be returned.  For example:
    • os:("Windows 10" AND "Windows 11") returns results associated with Windows 10 AND Windows 11.
    • os:"Windows" AND scanner_score:>6 returns results associated with Windows AND scanner score that is greater than 6.

  • Complex searches that cross Asset and Vulnerability terms with OR condition statements are not supported in the UI search box.
  • If searching across more than a single search term, only AND is supported.  For example:
    • cve:2020-2718 AND vulnerability_score:>80 is valid.
    • cve:2020-2718 OR vulnerability_score:>80 is not valid.
  • While asset search and custom field terms support negated search terms (terms preceded with a minus “-”), vulnerability definition terms do not.  If you try to negate (“-”) a vulnerability definition search term it might not produce an error, but the results may not be what you would expect.
  • It is preformant to search for terms when you nest the values together:  For example:
    • os:("Windows 10" OR "Windows 11") speeds up the search.
    • os:"Windows 10" OR os:"Windows 11" will be slower.

General Tips

Use an asterisk (*) for any number of characters or as a wildcard for a string used within double quotes. This will generate a case and location sensitive search. For boarder results follow Tokenized formatting. 


Use a question mark (?) in strings to represent a single space of any value.

To negate an asset search term or custom field use a minus sign (-). -os:"*Windows*" AND -os:"*Server*"
Using terms within parentheses will assume an "OR" between terms.   tag:("Alpha" "Bank" "RDP")
To search for a grouping of terms, use the plus sign (+) or (AND). In this case, a tag that contains both the word "Java" and the phrase "app portfolio". 

tag:("Java" AND "app portfolio")

Exclusive range queries are denoted by curly brackets ({}). This will exclude the beginning and ending 'values' within the curly brackets, so in this example it will return values of 2-9.

Range queries using square brackets ([]) will include the beginning and ending values, so in this example it will return values of 1-10. 

scanner_score:{1 TO 10}


scanner_score:[1 TO 10]

To search for assets that have or do not have data for a specific attribute, use the _exists_ parameter. Valid attributes are: tag, os, ip, hostname, url, mac_address, netbios, fqdn, file, fix, and application.  _exists_:netbios

or for does not exist


To escape the following characters, use the backslash (\) before the character. + - & |! ( ) { } [ ] ^ " ~ * ? : \
For dates, the formatting is year, month, day. due_date:2019-4-30
Use d, M, y to indicate day, month, or year. due_date:>now-7d
For search terms using time frames relative to now, think of the syntax as reading "prior to 7 days ago" (<now-7d) or "after 7 days ago" (>now-7d) helps to remember the correct syntax and order.



When searching more than one subnet, you need to put the subnets in square brackets ([]), separated by OR, and the whole search in parenthesis '()'.

You can also use CIDR block formatting for subnets. 

To exclude a few IPs, use the -ip: as shown. 

ip:([ TO] OR [ TO] OR [ TO] OR [ TO]) AND -ip:( OR

Brackets are not needed for CIDR ranges:

ip:( OR AND -os:(Cisco) 


Searches Supporting Cisco Vulnerability Management Research

These searches illustrate why using the Cisco Security Risk Score over Scanner Score or CVSS helps prioritize remediation and reduce workload. CVSS v3 scores includes both CVSS 3.0 and 3.1.

Vulnerabilities with a low scanner score, but a high risk score scanner_score:<=3 AND vulnerability_score:>75
Vulnerabilities with a high scanner score, but a low risk score scanner_score:>=4 AND vulnerability_score:<50
Vulnerabilities with a high risk score, but a low CVSS score vulnerability_score:>=80 AND cvss_v3_score:<=3
Vulnerabilities with a low risk score, but a high CVSS score vulnerability_score:<80 AND cvss_v3_score:>=7
Vulnerabilities with a high CVSS v2 score

cvss_v2_score:>=7 AND -_exists_: cvss_v3_score

Note: CVSS_v3_score includes both CVSS v3.0 and v3.1
