which fields are searchable ?

i’d like to help my listers by telling them which fields are searchable

is it title, short descrip (excerpt?), long descrip ?

are street addresses searchable (not just for maps but if you search for a street named New York Street, then if someone searches for New York that perhaps that listing is returned too?)

what about categories?

what about images titles, alt text?

if i can know all the searchable fields, i can tell my listers and this could help them with what content they provide

many thanks
