At the moment, I am trying “special tags” as a way to group documents across multiple databases for research projects.
To distinguish between the typical tags I use, which are always one word like GLM or Bayesian, I created a tag called: [MyProjRef] The brackets included. Thinking that the brackets would indicated a “project” tags.
I was able to add the tag to multiple documents just fine.
If I go into the Tags area on the sidebar, select a database, I can filer by that tag. I can also add it to my favorites.
If I try using the search capabilities via tag:[MRRVRef] this doesn’t work. No documents are returned. The same for iOS.
