How would you search in EconBiz?
No checkmark here: Use only meaningful subject-specific terms for the search (that’s why you e.g. drop revolution).
Tick: This way you can find more relevant hits. Use synonyms, and also broader and narrower terms.
This is ok for a start - but rather imprecise. Sharing and Economy are terms which frequently occur independently from each other - and without any connection to "Sharing Economy".
Databases usually only use the exact term you enter. Search for all word forms, e.g. with an asterisk at the end (state* = state / states ...).
Tick: The asterisk helps you find all the words that begin with Consum. With quotation marks you find "Sharing Economy" as one term (phrase).
That's a good idea! You can enter it as follows (the technical term for this is search string):
("Sharing Economy" OR "Share Economy")
