Make sure you spell your search terms correctly. Use multiple words Use multiple words when performing your search to narrow the number of pages found. Without the quotations, the search engine will return all documents that contain the four words, regardless of the order that they appear, or whether they appear next to each other in a document at all.
Quotation marks force the search engine to find exactly that phrase.
Use wildcards Wildcard searches can expand the number of matches for a particular search term. Use field searches Field searches allow you to located words found in a specific part of a document. The field name should be in lowercase, followed by a colon. There must be no spaces between the colon and the search term. Field searches must be either single word searches, or phrases contained in questions marks.
