ee_search_enddate(ee_dataset, enddate = Sys.Date())

ee_search_type(ee_dataset, type)

ee_search_provider(ee_dataset, provider)

ee_search_provider_list(ee_dataset)

ee_search_tags(ee_dataset, ..., logical_operator = "OR")

ee_search_title(ee_dataset, ..., logical_operator = "OR")

ee_search_tagstitle(ee_dataset, ..., logical_operator = "OR")

ee_search_title_list(ee_dataset)
