Use the Advanced search to find:
- all of the words;
- an exact phrase;
- at least one of the words.
You can also exclude search terms using the without the words option.
Search for your terms anywhere in the full article or limit your search to terms in the title of the article.
- anywhere in the article - will return a more complete set of articles related to your topic, but will also include more articles of less relevance because the term appears somewhere, but is not a major concept in the article.
- in the title of the article - will return a more focused, but smaller, set of results since terms in the title of an article tend to be major concepts in the article. Some relevant articles will be missed because the terms appear in the text, but not the title.
You can also search for an author, a particular journal title or restrict your search to within specific dates.
