tag search?

hi just a question ive been wanting to ask…

  1. an actor can have 1 or more tags right?
  2. you can check with ‘actor has tag’.
  3. if you have 2 or more tag, you just need to have 2 checks with ‘actor has tag’
  4. is ‘actor has tag’ searching / query-ing is recommended?
    i mean, like used a lot in checks /array… etc…

thinking if maybe add actor tag: bruce wayne
so for a fast search, find actor with tag ‘bruce wayne’
this is because i have 1 character class that branched of to different types of unit…
wanted to classify them , and is wondering which way i can quickly query/search for specific actors…
is this alright? or theres a better way to do this…
