I just experienced the same issue. @hziak: where are we on this?

pstoehr commented 8 years ago

Seems to work now, but recommendation for "ageRange" 0 and 1 always return an empty result list no matter what keywords are used.

chseifert commented 8 years ago

age range semantics: 0 - child 1- young adult 2 - adult

Currently there are no sources providing results for age range != 2
