Keyword vs. Subject

When you type things into database search boxes, you are, by default, doing what is known as a keyword search. When you are looking for information on certain topics it can be helpful to do a subject search instead. However, some databases' subject headers are not as robust or descriptive, so a highly targeted keyword search might be better in some cases. Here are some key differences between the two search types of searches:

Keyword Search Subject Search
  • searches anywhere in the record for the words you typed
  • provides a lot more, but possibly unrelated, results
  • useful if you know that you have the correct words
  • search is the same regardless of database
  • has been tagged by a librarian as being relevant to the assigned subject
  • provides fewer, but more relevant, results
  • useful when multiple terms describe the same idea (ex. drugs, pharmaceuticals, medication)
  • different databases might use different vocabulary
