I understand file beat is an aggregated `tail -f` command. But does it allow us to transform log-lines to a format whereby we can run searches (or queries) on elasticsearch (or kibana)?

Can file beat do such transformations? Or are these done elsewhere?

Please take a look at filebeat documentation. You can use processors to transform flowing data.
