Best way to do that would be to use the filters for sub-class in the
table. Click the filter icon beside the dimension name, click 'show
advanced', and then you have different options for the filter. I suggest
"contains any term" as that field is space delimited. So for example if
you put "laptops golf", it will bring in any subclasses that have
"laptops" or "golf" in their name. I think you can put up to 100 words
in that field.
