Why are some knowledge articles indexed and others not?Issue When a knowledge article is is created it should be indexed within a few minutes. This works for some articles but not others.CauseA common reason it's not picking up the articles is because you need a value for the Valid To (valid_to) field. Out-of-the-box this field is populated a default value:javascript: current.kb_knowledge_base ? new global.KBCommon().getDefaultValidToDateFromCurrentDate(current.kb_knowledge_base) : ''; But the field itself isn't mandatory. If you remove the value (or the default value configuration) it will not be picked up.ResolutionTo resolve this you need to ensure a value is selected when you submit the knowledge record.
