I don’t quite understand what function are you looking for…
Not quite sure I can follow you. Of course the Steinberg Help contains all Manuals of all their Products: so the filter function works nicely to filter down what you need.
But, as suggested by Daniel above, if you bookmark this Link to the Dorico Pro Help 5.1 English you land on the page with a search function. And the search is only on the actual Dorico Pro Help 5.1 English (Manual)
