Keyword Techniques: AND
When you are searching for articles and want to get fewer articles that are better focused on your topic, you can use AND to narrow the number of articles you see.
For instance, if you search for Public Health AND Policy, you will only see articles that have both keywords in them. If you add another concept (Public Health AND Policy AND Prevention), you will see even fewer results, since all articles now have to have all three keywords.
Some databases require you to capitalize AND when you write it out, so it's a good habit to get into.
Keyword Techniques: TRUNCATION WITH THE * SYMBOL
When you are searching for a word or concept with multiple synonyms or variations, use the * (also known as truncation).
When put at the end of a string of letters, * will search for words that start with those letters and give you articles that include every possible word that could start with those letters.
Examples include:
surviv* will get you articles using the words survive, survival, and survivors
nazi* will get you articles using the words nazi, nazis, and nazism
war* get you articles using the words war, wars, warfare, warplane, but also ward, warden, warner, warlock, wardrobe, warlord, warp, warehouse, warm, warn, warble, etc.
Keyword Techniques: PHRASES WITH " " MARKS
When you are searching for a concept, idea, or object that can only be described or named with multiple words, put the words in "quotation marks" when searching in a database.
Examples include:
"French Resistance", "global warming", "accounts receivable", "musical theater".
Avoid phrase searching with quotation marks where the phrase is not a common turn of speech, where there is only a single word, or where descriptive adjectives are used.
Examples include:
"beautiful artwork", "spreading propaganda", "terrible disease", "how a bill becomes a law", "United state's economy"
