When you search library resources, you will use keywords related to your research topic. Watch the video to the right to see how to break down your topic into lists of usable keywords. We call these your "search terms."
When you have a list of keywords, you'll need to combine them. The rest of the information on this page gives examples and tips for combining search terms in order to narrow down your search results.
Remember that the database can't interpret what you mean, so you have to be clear and specific with your searches in order to control the results.
In addition to "phrase searching," Boolean operators, and truncation, you can also try using wildcard searches.
Like truncation, wildcard searches will expand your results. Wildcard searches allow the database to replace the wildcard symbol with any letters that would make up a real word. It's like a shorthand way of typing every possible word that fits the pattern with OR in between. Not only will this save you time, but it might also give you alternative keywords you hadn't even thought of.
Here's a table to illustrate how some of these symbols (including the truncation asterisk) typically work.
|Symbol||What it does||Sample search||Instead of typing|
|*||replaces zero or more letters at the end of a word
(this is truncation)
|comput*||computer OR computing OR computational OR...|
|#||replaces at most one letter||ne#t||net OR neat OR next OR nest OR...|
|?||replaces only one letter||b?t||bat OR bet OR bit OR bot OR but OR...|
REMEMBER: Some databases may use these symbols differently or may use different symbols, so check the database's help section if you're having problems with wildcards.
