The OPAL catalog will open to the Advanced Keyword Search box. It is a series of search bars connected by Boolean operators (see View Search Tips box) that searches records describing the items available through the library (see Fields box)
The catalog has multiple ways to keep out items you don't want from your search results.
If you open "Limit your search (optional)," you get a few more options.
Open the View Search Tips to learn about different search tools you can use in OPAL. In particular, you should pay attention to:
Catalogs were designed to provide access to physical items in the library, so they cannot search the item itself. Instead, they search records that describe the original item. Each record is broken into different parts that offer multiple ways to describe the item. These parts are called fields. The catalog will automatically be set to search all fields, but you can instead select to just search in the title (will also search the table of contents if available), the subjects (categories selected to describe the item by librarians), and the author(s).
The Title, Subject, and Author fields are different from the Title, Subject, and Author searches in the Other Search Types section because the field searches will look for what you search anywhere in those fields, while the other searches look for them in the exact order you type them in. You should use the other searches when you know exactly what you are looking for, and use the fields if you don't.
