The ability to use substring or regex matching inside Port’s search rules, especially when the target property is an array of strings (such as tags).
This could be via:
  • a dedicated operator like containsSubstring / matches, or
  • allowing regex patterns in value (e.g. ^service:{{serviceTitle}}).
{
"property": "tags",
"operator": "matches", // or similar
"value": ".
{{ .event.diff.after.title }}.

}
