The customization of the search categories to be displayed in the Advanced or Simple Search is solved very very awkwardly. 3 clicks for each category is just too complicated.
My suggestions:
- Make activation switch directly operable
- Make list sortable by activated terms
make
- Checkboxes for the terms in both columns for advanced and simple search
- Improve the explanation in the KB, because
translating "dc:Title" with "Dc Title" has no added value. An explanation that dc:title B is e.g. DUBLIN CORE title would be super, so that one knows what one activates there.

Please improve at least the KB urgently!
Thanks!
