Advanced Search Filter


Role Availability	Read-Only	Investigator	Analyst	Manager

The Advanced Search filter enables you to enter a search value on a selected field. The following table shows the filter fields that you can find in the first drop-down list. Advanced Search Fields (First Drop-Down List)

Filter Name	Meaning
Name	Filter assets by the name of the asset.
Description	Filter assets by the asset description.
UUID	Filter assets by the universally unique identifier (UUID).
IP/CIDR	Filter assets by IP and Classless Inter-Domain Routing (). This is a method for allocating IP addresses and routing IP packets. It is the range of IP addresses that define the network.
FQDN	Filter assets by Fully Qualified Domain Name (FQDN).
Asset Type	Filter assets by asset type.
Instance Type	Filter assets by instance type.
Region	Filter assets by region.
Operating System	Filter assets by operating system.
Service	Filter assets by service.
Software	Filter assets by software.
Associated Plugin	Filter assets by the plugin associated to the asset.
Alarm Counter	Filter assets by the number of alarms.
Event Counter	Filter assets by the number of events.
Vulnerability Counter	Filter assets by the number of vulnerabilities.
Configuration Issue Counter	Filter assets by the number of configuration issues.
PCI Asset	Filter assets by Payment Card Industry (PCI) Asset, if the asset is included or not in the PCI Data Security Standards (DSS) Asset Group. See Asset Group List View and Working with Assets and PCI DSS for more information.
HIPAA Asset	Filter assets by Health Insurance Portability and Accountability Act (HIPAA) Asset, whether the asset is included in the HIPAA Asset Group. See Asset Group List View for more information.
Custom User Fields	Filter assets by the fields you have created. If you have not created fields, this filter does not display.

Note: The result of a search when you use the Alarm Counter filter or the Event Counter filter depends on if an alarm or an event can identify the source or destination as an asset in the inventory. Your environment can have alarms or events associated with assets both included in the inventory and those not included in the inventory. Assets included in the inventory display their names in blue, and assets not included in the inventory display their names in gray. The alarm and event counter filters only count the identified (blue) assets.

Important: The alarm and event counts are not updated in real time but are calculated every hour. If the counts are not updated, it can happen because new events or alarms are in your environment after the last count.

The following table shows the operators that you can find in the second drop-down list. Advanced Search Fields (Second Drop-Down List)

Operator	Meaning
>	Greater than.
>=	Greater than or equal to.
<	Less than.
<=	Less than or equal to.
Equal	Equal to.
IP Range	Range of IP addresses.
Is Empty	Include assets with no IP addresses. This operator is available only for IP/CIDR.
Is Not Empty	Include assets with IP addresses. This operator is available only for IP/CIDR.
Like	Search for the specified pattern.
Not Equal	Not equal to. Important: Some filters don’t include the NOT operator (for example, Services or Software).
Not Like	Not true.

The following table shows the operators that you can include in your query string. Use the search field to enter queries and refine your search. You can enter free text, use wildcards, and use advanced search syntax. When searching, keep in mind the accepted query string syntax list in this table. Accepted Query String Syntax

Type of Query	Meaning	Example
Standard query with a blank space between terms	By default, a space between query terms is considered an implicit “OR”.	denylist malicious
Literal, using double quotes `" "`	Matches fields that contain the full term. Literal searches are case-sensitive. Note: This type of query will not match any searches in the raw log because raw logs are tokenized. Note: IP addresses and FQDNs are considered literal searches, so they don’t require quotation marks.	”Event from asset not received”
Boolean operators or using parentheses `AND`, `OR`, `NOT`, `( )`	Including AND or OR between two search terms will search for results that match both of those terms. Including NOT between two search terms will exclude results that match the second term, even though they otherwise match your query. Parentheses can be used to group terms for higher precedence relative to the rest of your query. Parentheses are also used to designate subsearches.	(http OR tcp) AND ftp
Wildcards, asterisk `*`	Appending an asterisk to the end of a term within your query will search for results that begin with your search term. An asterisk cannot be used at the beginning of a search query.	instance*
Wildcards, question mark `?`	Embedding a question mark in the middle of a term will search for results that otherwise match your query, no matter the value in the position held by the question mark in your search term. A question mark cannot be used at the beginning of a search query.	qu?ck
Regular expression (regex), using `/expression/`	Regular expression inside forward slash characters. A dialog box opens to confirm the search. Note: The characters `"`, `*`, `?`, `(`, and `)` are special characters included in expressions. If you want to search by these characters, you need to manually escape them by preceding them with a backslash.	/Describe.*Instances/
OTX pulse	Pulses are collections of Indicators of Compromise (IOCs). You need to insert the word `pulse:` followed by the pulse ID or URL.	pulse:59432536c1970e343ce61bf0

Any characters may be used in a query, but certain characters are reserved and must be escaped. The reserved characters are these:

- = & | > < ! [ ] ^ ” ~ : \ /

Use a backslash (for example, ”>”) to escape any reserved character (including a backslash). To search assets using the advanced search filter
