Hi all: I'm trying to define a filter for a bibliography, but I can't do it right. In the *Biblatex* manual, in *3.5.8 Bibliography filters*, appears this example: * **\defbibfilter{example}{% * *\( \type{book} \or \type{inbook} \) * *\and \keyword{abc} * *\and \not \keyword{xyz}} *
And —I'm not sure— I supose it's just like *\defbibfilter{example}{\( \type{book} \or \type{inbook} \) \and \keyword{abc} \and \not \keyword{xyz}} * I want to create a filter like "write in this bibliography all the references with the keyword *General*, but only those without the type * electronic*":* \defbibfilter{General}{\keyword{General} \and \not \type{electronic}} * And later, where I want the bibliography \printbibliography[filter=General] \nocite{*} Am I writing it correctly? Regards Antonio
