durchsuchen vs suchen
to search / look for
'suchen' and 'durchsuchen' both have to do with wanting to find something. 'suchen' is more general: you do not know where something is and try to find it. That can be a key, a person, or even an answer. 'durchsuchen' means that you search a place, a bag, a file, or a lot of data thoroughly and systematically. Learners may confuse the words because both describe a search. The practical difference is: you look for something, but you search through an area or thing where you think it might be.
