There are 2 methods available for searching the library catalog. The first one is SIMPLE SEARCH, which is the simplest method of searching the catalog: you just enter any keyword, whether contained in document titles, authors name, or subjects. You can supply more than one keywords in Simple Search method and it will expand your search results.
ADVANCED SEARCH, lets you define keywords in more specific fields. If you want your keywords only contained in title field, then type your keyword in Title field and the system will scope its search only on Title field, not in other fields. Location field lets you narrow search results by specific location, so only a collection that exists in selected location is searched by the system.
