Search Tips & Examples

Best practices for building search queries

Combining Filters

Use spaces to combine multiple filters:

domain:kaspersky.com port:443 tech:nginx

Exact Matches

Use quotation marks for exact phrase matching:

http_title:"Login Page"

Wildcard Search

Use * for wildcard matching in certain filters:

subdomain:*.kaspersky.com

Advanced Queries

Build complex queries for precise asset discovery:

domain:kaspersky.com is_cloud:true port:443
