In the Library Catalog, do a keyword for 'health physics' (without the quotes), or for any other topic of your choice. Scroll through the results.
Some results will be obvious--the search words are in the title of the book (or article, or video, or report, etc.) Some won't be so obvious. Click on a less obvious result and look for your search words in the record--they should be highlighted in yellow, as in the picture above.
Try searching for the same thing in the Title or Subject field using the Advanced Search. Did you get anything? (These are more precise fields, with more rules and fewer options.)
Library databases work the same way. Our databases (the library catalog is a database, too) contain information ABOUT articles and books (and other things), such as:
When you search the library catalog, you can search, for instance, for a TITLE.
This looks only in the fields for:
A KEYWORD search, on the other hand, searches any of the "word"-related fields:
(Note: the keyword doesn't search all the words in a record. For instance, it doesn't search for publisher names.)
(And we don't do ads!)
Different academic topics may use different lists of subject terms, usually called a "Thesaurus".
This is the Subject terminology for Heart Attacks in the general database Academic Search Premier. They use the term Myocardial Infarction, the medical term for a heart attack, to be more specific, but the topics are still fairly broad.
A medical professional searching for medical articles needs extra precision, so the terminology is more specific. This is the Subject terminology for heart attacks in CINAHL, the Nursing database.
Because CINAHL is a medical database, using medical terminology works better and gives us all the articles about heart attacks, not just the ones that use that phrase.
But now there are so many results, what do we do?
Use the other options in the Advanced search to get more specific. Each option selects different fields and different entries within each field. Here's a search for:
How do you use these terms?
You can look them up in the Subject Headings or Thesaurus in many databases. (In CINAHL they are called CINAHL Headings, and in Medline, MeSH.)
It's possible to construct very detailed searches, but you can also just use the terms as your search words. In an individual record, you can also click on a single subject heading to do a search--then use the options on the left of the search results to get more specific.
