Hi all, Side by side with notions of "tag", "field", "subfield" there is the notion of "indicator" in the "Koha 3.14 Manual (en)" (see section 1.4.1. Display, subsection 1.4.1.2. hide_marc). What does "indicator" define in context of MARC formats ? What is this parameter applied for ? Thank you in advance, Gennady
