        /* 
         * Depending on what server type you are using, filters are be one of the following:
         * 
         * 1. ActiveDirectory or Other
         *    - LDAP query/filter syntax
         *    - Read more at: http://bit.ly/2qyLpzW
         *    - ex. "(&(givenName=John)(|(l=Dallas)(l=Austin)))"
         *    
         * 2. AzureActiveDirectory
         *    - OData syntax for a Microsoft Graph query parameter '$filter'
         *    - Read more at http://bit.ly/2q3FOOD
         *    - ex. "startswith(displayName,'J')"
         *    
         * 3. GSuite
         *    - Group Filter
         *      - Custom filtering syntax that allows you to exclude or include a comma separated list of group names.
         *      - ex. "include:Group A,Sales People,My Other Group"
         *         or "exclude:Group C,Developers,Some Other Group"
         *    - User Filter
         *      - Custom filtering syntax that allows you to exclude or include a comma separated list of group names.
         *      - Allows you to concatenate a GSuite Admin API user search query to the end of the filter after delimiting
         *        the include/exclude filter with a pipe (|).
         *      - Read more at http://bit.ly/2rlTskX
         *      - ex. 
         *         or "include:joe@company.com,bill@company.com,tom@company.com"
         *         or "exclude:john@company.com,bill@company.com|orgName=Engineering orgTitle:Manager"
         *         or "|orgName=Engineering orgTitle:Manager"
