The Qualys Query Language (QQL) supports the following logical or Boolean query operators. Use these operators in your queries to narrow down or broaden your search.
Narrow down the search by using the and operator in the Boolean query. The result contains all the token values that are provided in the query.
Example
Show the certificates issued by DigiCert and will expire in 30 days
certificate:(expiryGroup:In 30 Days and
issuer.name:DigiCert)
Narrow down the search by using the not operator in the Boolean query. The result contains all the other values except the one specified after not in the query.
Example
Exclude the certificates that are issued by Qualys in the search result
certificate:(not issuer.organization:Qualys)
Broaden the search by using the or operator in the Boolean query. The result contains any of the token values that are provided in the query.
Example
Show the assets having an operating system as Windows or Netscaler
asset:(operatingSystem:Windows or operatingSystem:Netscaler)
