Articles do not appear on $knowledge.do past valid to dateIssue By default, knowledge articles that have exceeded their valid to date are no longer searchable on the ITIL knowledge homepage or in contextual search results. Is there a way for developers to allow users to search for articles that have exceeded their valid_to date?CauseCurrently, a query on the valid_to field on $knowledge is hard-coded in the platform and cannot be removed from the front-end.ResolutionThis behavior is as designed. The only option is to change the valid_to field date or, if you need this for some other cause, create a new field for that and move the data to that new field.Related LinksThis blog post in our Community provides a possible workaround that may help you: Adding an expiration date to Knowledge Base articles
