local colabfold_search: Ambiguity in README regarding db-load-mode with vmtouch

[mf-rug]

The README states "If the index is in memory use to --db-load-mode 3 parameter in colabfold_search to avoid index loading overhead. If they database is already in memory use --db-load-mode 2 option."

Besides some language issues here, this is not clear, right? "if index in memory use 3" and "if database is in memory use 2". Is the database and the index not the same? In the mmseqs manual p21, it uses mode 2 after mentioning the vmtouch command, but it's not clear whether vmtouch is a required step or optional and if the mode then is supposed to change.

Thanks a lot for your help.
