Web Search Alerts result feedback can suggest negative filter phrases for unwanted hits.
Open a Web Search Alert result list and use Suggest filter in the feedback column. Tools looks at the alert instruction and the stored result title, summary, match reason and source name, then proposes short phrases that may explain why the hit is unwanted. The suggestions are intentionally narrow when a result appears to be a wrong person or a similar-name match.
Selecting a suggestion only fills the Optional negative word / phrase field. It does not dismiss the result and it does not change the alert. The result is dismissed, and the negative phrase is saved, only after the user presses Dismiss.
Suggestions are cleanup aids, not automatic moderation. They never save a filter term, hide a result, or change an alert on their own. Review the suggested phrase, adjust it if needed, and then choose Dismiss when the phrase should be saved as a negative filter for future runs.
This keeps the user in control while making repeated cleanup faster.
