For advanced queries, see our Search Help page.

In an advanced search, you can search for terms in specific fields: anywhere, authors, title, abstract, keywords and affiliations.

• Anywhere: the full text of the article, along with all the following fields. 
• Authors (last name or last name, initial): last name (and, optionally, initials) of the article's author. A search in this field will not find authors cited in the article or book content. 
• Title: words (and their stem-related cognates) in the article or chapter title. 
• Abstract: text in the abstract of the article or chapter.
• Keywords: descriptive terms used to classify the article. 
• Affiliation: the authors' affiliation.

Enter your search term in the box, then select your field from the drop-down menu.  You can search across more than one field at a time using the Boolean operators given in the AND/OR/NOT drop-down menus. 

If a search involves terms in multiple boxes, the Boolean operators between the boxes are interpreted in the order in which they appear.  An advanced search provides these other features:

• Select one or multiple publications to be searched instead of all.
• Limit the search to issues published within a time frame.
• Specify whether the results should be listed by date or by relevancy.
• Choose how many results should be displayed on each page.
• Review and rerun searches you performed earlier during this session. (The session history is cleared when you log out.)
