Farcaster Devs

i have my hub running

i want to extract from its current state all the casts that meet a certain condition (let's say they have the string $bleu inside its text), and save all those casts on on that same machine

how would you do this?

what's the equivalent of a for loop to check all this info?

maybe @arfonzo can help? i don't know the best way, but what comes to mind (not sure if possible): streaming all casts over grpc in reverse order with a cursor

For castback my backup and search tool, I call castsByFid to stream all casts and cache them on filesystem for offline search.

There may be a way to set more advanced filters via an API call, I'd start there to check the API specs! I'll try to look later if I have some time.
