How to reprocess/reparse all logs?

[dss010101]

Hi,
this is probably due to my lack of the stack...so why im asking here.
As im working through to figure out the transforms and how/what to parse into labels - find that i need to reparse old logs that have already been parsed - as there may be additional labels that im now extracting.
It's not clear to me how to do this - right now, i basically do docker-compose down followed by a force pruning of the volumes.
Is there a better/cleaner way of telling vector to reprocess/parse all logs?

Thanks
