Basically, you would have many occasion to write query on search bar. You can simply type some keywords to list all logs on the interface. However, the results will also include other data which has the same keywords but with irrelevant properties you have wanted to see. For example, If you only type an IP address without properties or column name Logsign will show you all logs including the IP regardless of Destination.IP, Source.IP or EventSource.IP. So, If you want some specific log lists you need to know how to make efficient query. You can see the basic form and examples as below.

value OR another_value
