I hope the following can help you understand the logs. Let's say you are typing 'Value' in the Smart Search bar. In order to give you results as you type, Qlik Sense is searching successively for 'V', 'Va', 'Val', 'Valu', 'Value'. In order not to overall the Engine with queries, we cancel the queries that are not valid anymore ('V', 'Va', 'Val', 'Valu'). The cancellation is then listed in the Audit log.
