A user can set up 100 tags total per account. Should a user try to set up a 101st tag they will be prompted with an error message telling them they need to delete an old tag before they can set up any more tags.
There are two options to choose from when omitting Tags:
"Exclude records with ALL of these tags" – using this select will exclude tagged records from the search using "and" Boolean logic (i.e. I want to exclude Tag A and Tag B records.)
"Exclude records with ANY of these tags" – using this select will exclude tagged records from the search using "or" Boolean logic (i.e. I want Tag A or Tag B records.)
