Don't use all the fields. If a field is left blank, it will match any entry. It's also possible to enter just a single word or even a part of a word.

Example: To search the Database for information on muscles just type "muscle" first in the title field. Click on Find. Next, type "muscle" in the abstract field. Click Find. Search both title and abstract but separately. To find citations added this year, search 2009 in the title field. To find all the work by an author, type the last name in the author field.
