Hi Andrew, is the + needed before the last tag-section?
[tag[Date Operators]] [tag[each Operator]] [tag[Editions]] +[tag[Filter Operators]] +[sort[]] works for me on
tiddlywiki.com[tag[Date Operators]] [tag[each Operator]] [tag[Editions]] [tag[Filter Operators]] +[sort[]] gives more results (sorted)
Good luck!
Thomas
