Was reading the help documentation and noticed that there is a way to pass in comma separated tags to a query template:
One or more tag names to be queried
String Or String List
The name of a tag in the underlying data source. This parameter can be repeated multiple times in a URL if multiple tags are to be queried, and multiple tags can be passed in a single parameter as a comma-separated list of tag names.
I tried this from a BLT and it didn't work. What is the trick to get this to work? I have about 50 tags to query and I dont want to hard code the mappings and I would rather not fire 50 individual queries.
