Keyword Highlighting


When keyword highlighting is supported in the contextual summary for a sensitive information type or a trainable classifier, in the Contextual Summary view of activity explorer, the keywords in a document that were matched to a policy are highlighted.

  • The regular expression Regex_portugal_citizen_card finds content that matches the pattern.
