I am using loki data source and fetching RAW system logs.
in dashboard I have search bar to search some string/number in RAW logs.
In query I am using variable “(?i)$search”.
Previously, it was highighting the string/number searched in RAW logs, but now it does not.
Instead of variable in query, If I use static value e.g. “5002” it highlights in RAW log.
Any idea why it is not highlighting searched keyword, when variable is used in the query?
