On the Advanced search form, you can create a search using field codes, proximity operators, or boolean operators to narrow the scope of the search.
To create an advanced search, Click "Advanced Search" from the main search page

To search for keywords in an article's title or abstract, type in TITLE-ABS before your search terms. Be sure to use parentheses! For example, this is correct: (TITLE-ABS( children OR pediatrics)) but this is not correct: TITLE-ABS children OR pediatrics
When doing a Boolean search, Scopus insists that parentheses be used correctly. If you get a message about a Syntax Error, check your (( )).
Scopus needs Boolean operators (AND, OR) to be capitalized. To exclude in Scopus, you must use AND NOT (not just 'NOT').
