How does prefix and filter work exactly? #30

Prefix what exactly? Filter what?

From the docs I don't understand what they do. They don't seem to do anything for me (always empty set) or return a similarly arbitrary list of messages. I am pretty sure this is due to me using it wrongly, but I struggle to understand how it's meant to be used.

What is the prefix applied to? The name of any stream in the log group?

What is the filter exactly applied to? Full text search over the stream's content?

I resolved my main confusion, it was caused by a positive start time when using get. No wonder I never got anything displayed. :)
