Thanks you Eric,
Excellence as usual.

Yes, that is more accurate. I should have said 'two or more space-separated
values [...]
Are fields different from tags in that each individual space-separated value
have to be surrounded by [[double brackets]]? My experiments lead me to
believe this, but it might be the way that I have presented my problem in
the first place.

This is a string variable prepared to the format which
store.filterTiddlers() can handle. -
"[tag[val1]][tag[val2]][tag[val3]][tag[val4]]"
It can be seen that "[tag["+val.readBracketedList() means "take val, the
array of values in field1, and read them as a bracketed list.
But what about .join("]][tag[") ?
This is added to the string so that [tag[]] is added to the end of each
item, each time the for loop loops over the tiddlers.
What I don't understand is why [tag[]]
is needed. Why not just [tag["+val.readBracketedList()]]
I've tied to work back from the solution to learn how things work. [1]
Best Wishes
