The results from the selection of multiple categories is confusing e.g. a Search for "Solomon's temple", All Images in IDBS** gives 1 result:
- select Maps or Site Plans, or both --> image appears
- select other categories one by one --> image does not appear
- ensure All Images is displayed
then
- select Site Plans and all categories below --> image appears
- deselect Site Plans --> image disappears
- select Site Plans --> image appears
- select Photos or Portraits --> image disappears
- select Photos and Portraits --> still no image
- select Maps --> image appears!!
Multiple selection acts like OR initially, reverts to AND, and finally to OR.
It would help if there was a single box to select/deselect all categories, as with Search Fields.
