Understanding log settings

Hi I have some confusion on the log settings. Specifically what this setting is doing and how it is related with the rest of the log settings:

index.search.slowlog.level: info

If I'm understanding the rest right, these would output the warn/info/debug/trace log if the queries surpass the specified thresholds.

index.search.slowlog.threshold.query.warn: 10s
index.search.slowlog.threshold.query.info: 5s
index.search.slowlog.threshold.query.debug: 2s
index.search.slowlog.threshold.query.trace: 500ms

But then how does the index.search.slowlog.level: affect the rest of the settings?
