I want to add cer device type to the following string to search for both. Boolean expression?
index=cisco cdnt* partial service
By default all filters (separated by space here) are using AND boolean expression. you can just add your devicetype string (if its not an extracted field) OR devicetype="valuehere" (if its an extracted field).
Yes, with implicit AND between all search terms. Examples;
will return no events. host cannot be both 'alice' and 'bob' at the same time.
(host=alice user=david) OR user=cecilia
will return all events from host 'alice' where user=david, and all events where user=cecilia, regardless of originiating host.
will return all events from the host 'sales', if the events contain the field 'price' and the value is not '55'.
host=sales NOT price=55
will return all events from the host 'sales', that don't contain price=55, even events that do not have 'price' in them at all.
and so on. See more in the docs.
