I used the wrong word I see now. Indeed I meant parentheses () and not brackets [].

You are right that your suggestion “lake seawater” does solve the problem, so it is definitely not a bug :-).
Using a space between the parentheses would also solve the problem: “Lake ( Seawater )” instead of “Lake (Seawater)”. However that is still a (kind of a) work around ;-).

My request was more to avoid the above work arounds, if you should be able to search in parts of Tabble-strings, regardless the use of spaces or (accidental) typo’s.

Thx for your reply Maurizio!
