Be sure to use Caps for AND, OR, NOT when searching.
AND - searches for books and articles containing both terms. Example: Gandhi AND education
OR - searches for one of the words. Example: politics OR policies
NOT - exclude a term. Example: NOT Kasturba
Parenthetical notes () - excellent for OR or NOT searches. Like a math equation, the database will do this part first.
Example: Gandhi AND (education OR educaitonal) AND (politics OR policies)
Quotation Marks ""- Links words together in the search. Works best for phrases or proper names.
Example: "Mahatma Gandhi"
Example: "higher education"
Warning: You might exclude results. A search for "Mohandas Karamchand Gandhi" will omit results for just "Mohandas Gandhi" or "MK Gandhi"
Asterisk * - Allows you to search several word endings at once, without using OR repeatedly.
Example: India* will cover: India, Indias, Indian, Indians, Indianization
Warning: You may get unexpected results. India* will also bring up results for Indiana.
Many Databases have extra hidden search commands that only work in their database. These are extremely useful BUT differ between databases, so consult the directions for each database before using these commands.
Proximity searching is especially important for newspaper databases. Instead of AND use NEAR# or N# (depending on the database) so your keywords are in the same news story, not in unrelated stories/columns. 10 to 20 words of proximity is a good bet.
Please note that many databases works differently, so you need to read the about page. For example:
