The PsychSpider Advanced Search capability offers you the ability to join search words (terms) from the input line using operators. Simply select the desired Boolean operator from the selection box.
A click on an identifier's checkbox activates its collection for search. A collection is a pool/group of already searched and indexed documents. A more detailed description of the contents of the various collections can also be found on the help page.
Tip of the week: White spaces between words are treated as an AND Operator, except you have put quotation marks around your search term (Tip 9).
