You can search the database using either a drug name or a synonym. You will be redirected to the specific drug record if the drug is found by name or synonym match. If not, a PubChem search is performed to fetch structure of the input provided. In this case, five most similar drugs from the database are reported.
Instead you could search the database by providing (or sketching) the structure of your interest. You can choose among different search strategies and look up for: similar drugs (similarity search); identical drugs (exact search) or drugs containing your input structure (substructure search).
