Hi Alvareh, Many thanks, nice solution. I added values.js and it works fine. By the way I understood the bottleneck is the lookup-index maco in my solution For 2000 entries TW quickly freezes. I work to see how to use an alternative approach for that part.
Amazingly TW has indexes filter operator but not values! Isn't it worth adding it to the Tiddlywiki core?
