I am trying to figure out if its possible to create a dynamic item set by searching for specific tags in the metadata. For example, I want a page for all items from the 70s, another page for all musicians, then to be able to specify from their just musicians from the 70s without having to manually organize the data that way.
You could also do something like this within a site using the “Browse preview” block for a page: the browse preview block lets you specify a saved search, show results from it, and link to the full result set if desired.
