system tags

I like Apple ecosystem’s tags because they allow me to bring together files from diverse data sources.
However,

  1. it seems that I have to manually execute the command for reindexing Devonthinktogo database in order to make visible in Files app the tagged files from Devonthinktogo. Is this correct? or is it done automatically in specific time intervals?
  2. When I use my Mac, the tagged Devonthibk files do not show up under the respective tag (in Finder). Am I missing something here?

The Tags shown in Files.app aren’t coming from DTTG. They are coming from the Mac.

If you tag imported files in DEVONthink on the Mac, they are not going to show up in Finder tags. Tags aren’t written to the filesystem unless files are exported or you’re tagging indexed files in the database.
