Can a textbook have 2 different isbn #?

I'm looking for a book but when I search it by isbn, it shows a similar book but with a different number but the same name. Do you guys think I should buy it?|||A textbook can have two different ISBNs, but the one would then be ISBN-10 and the other ISBN-13. However, various editions (international vs US edition, for instance) can have different names, despite being the same book (with the same ISBN).
