In OCP console while filtering the logs, its observed the logs with level default,metadata,notice,etc are not displayed when we filter the logs using severity unknown

4.14+

100% reproducible

    1. Deploy a cluster with loki
    2. create a test application,make sure it has log with level as default
    3. Filter the logs with severity set to unknown
    4. No data is played, Change teh query manually and set level to what is there in the logs
    

Logs filters working incorrectly

Unknown level should display logs with all the loglevel

I would also request to change the name of the filter from unknown to unclassified which will display all the log with level that is not equal to any of critical/error/warning/debug/info/trace

Query to be used

{ log_type="application" } | json | level!~"(?i)critical|emerg|fatal|alert|crit|error|err|eror|warn|warning|debug|dbug|info|inf|information|notice|trace"

{ log_type="infrastruture" } | json | level!~"(?i)critical|emerg|fatal|alert|crit|error|err|eror|warn|warning|debug|dbug|info|inf|information|notice|trace"

{ log_type="audit" } | json | level!~"(?i)critical|emerg|fatal|alert|crit|error|err|eror|warn|warning|debug|dbug|info|inf|information|notice|trace"
