I want to create a search View in Toolset using the classic editor to allow for more detailed filtering, as I am more comfortable with that interface.
Solution:
Enable legacy Views by going to Toolset > Settings > General, checking “Show both the legacy and Blocks interface and let me choose which to use for each item I build”, then reload the page to access Toolset > Views, where you can build the search View using the classic editor and shortcodes.
