Searching Multiple Online Resources
You can save time by searching multiple online resources at once. It is, however, important to understand the limitations of doing so, because different providers have different capabilities.
As soon as you select multiple online resources, Citavi determines which search fields and options the selected online resources have in common. Citavi then presents only the fields and options that will work for all the selected resources, which may be significantly fewer than an online resource offers when selected by itself. If you need to perform complex searches involving truncation and operators, you may need to search each online resource individually.
