The information in the bracket informs us, If there is [LOCATION], it means only Project location has been searched. If there is [MAP], it means that the Project map has been searched. There is a third option [REPOSITORY SEARCH] that will tell the user the repository search was used, and it will contain other filter information.
For example, if you do a repository search on repository Test, the info bar can look like this:
Test [REPOSITORY SEARCH] | element: all elements | type: all types
