Ordinarily, each run of a filter expression starts out with the "source" tiddlers being those prevailing where the filter is being evaluated, which is normally equivalent to "[all[tiddlers]]". The plus sign causes the "source" tiddlers for the following run of filter operators to be the aggregate of all the results so far. So, in this case, including the plus sign makes the filter equivalent to: [[french]listed[courses][A2]listed[levels]] >> Isn't that the old regexp syntax that has been removed in 5.0.17? > Indeed. I didn't know it was supposedly removed, its why I use it, and it still works in 5.1.5-prerelease. It turns that I forgot to remove the regexp support before the end of the beta (I did add the new regexp filter operator which is intended to replace it). I think now we'll have to keep the existing support. > I think with proper set operators and/or variables which could hold sets, stuff like this could be enhanced. We're halfway there in 5.1.5. Variables can now contain lists, but there's not yet a syntax to retrieve a list from a variable and use it within a filter.
