How to Search:

You may use Boolean operators or, and, and not and also parentheses to form a search expression.  For example if you enter laelia anceps, the search engine will return a list of all documents that contain laelia or anceps, because the search engine treats a blank space between two words as the or operator.  If you enter  laelia and anceps, you will receive a list of all documents that contain both laelia and anceps. You may use the not operator to exclude documents that contain a certain word: if you enter laelia not anceps, you will receive a list of all documents that contain laelia but does not contain anceps.
