I created ca. 600 articles with identical format, describing different reed organs. I need a search tool to find the set of organs (article idents) that fullfils a combination of a fixed number of predifined search criteria, such as: "show me the list of article idents of organs of a given manufacturer, produced within a given period".
Could I make use of K2 to produce such a facility?

Hello Willem,

For this sort of functionality you will need an extension which offers advanced searching for K2.

You can browse the JED or here: getk2.org/extend
