3.5 Field Searching

Most search engines and databases search "words anywhere" or "keywords" automatically unless you select another type of search.

Keyword searching finds matches for your terms in any field of a record or any part of a Web page, so you will typically retrieve more information with less precision. This is known as "recall" searching because it focuses on recalling as much information as possible.

Databases and search engines may allow searching in specific fields such as author, title, url (Web address), or subject and will sometimes refer to this as "advanced," or "expert" searching. These searches will typically retrieve less information with more precision. This is called "precision" searching because it focuses on finding only precisely what you need.

For example:

If you are a detective and the only clues you have for a missing persons case are the words "red," "blue," and "green," these people could be a match. This is keyword searching.  

If instead you knew your person had a red tie, blue shirt, and a green beret, you have a better chance of finding the right person. This is field searching.
