Advanced Search Help

The standard selection is the search method with an AND-Operator.

The search engine supports the following search operators:

	AND,		If you have used a search term that is too general, you can combine different search terms using AND. By combining search terms in this way, you can further restrict your search and reduce the number of search results. For example: einstein AND gravity searches for all titles that contain both "einstein" and "gravity".

	OR,		To broaden your search operation, you can combine search terms by using OR. This method searches for you search terms both simultaneously and independently. For example: einstein OR gravity searches for all the titles that contain either "einstein" or "gravity" or both.

	NOT, -		To restrict a search operation you can combine search terms by using NOT. This excludes specific subjects from your search results. For example: einstein NOT gravity finds all titles that contain "einstein" but not the term "gravity".

?, *		Replaces a random number of characters. For example: use* will find "use", "user", "user-friendly"; organi*ation will find "organisation" and "organization".
