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: Search Engines like PsychSpider follow links within documents to gather more documents. A document can only be found by the search engine, if a hyperlink exists or the search engine knows the exact URL. If you can't find a specific document (i.e. "Psychoanalyse im Wandel der Zeit"), but you know who has published it (i.e. Universität Trier), PsychSpider might help you to get a contact address, so you will be able to request the document via telephone, letter or E-Mail.
