Input parameters (Set, Get): FILTER_TAGS

Output parameters (Get only): TASKS, UNIQUE_TAGS

Set this parameter to an array of tags used to filter the queried tasks. The QueryTaskCatalog task returns tasks that meet the criteria for all specified tags, not just some of them. The tags are not case-sensitive. If no results are found, TASKS and UNIQUE_TAGS return a value of !NULL.
