• Think up a few synonyms that describe your topic. Think about how scholars might discuss it, and if there are various spellings or translations that could come up in a scholarly article or book on your topic.
• Look out for Advanced Search forms (usually they have multiple search boxes). These can be useful for running 1 search that looks for articles matching any of those synonyms.
• Once you're comfortable with Advanced Search, you can run complex searches that try a lot of possibilities at once. Look for a Search History link, and you might be able to "cross" your various searches to find sources that include both sets of keywords, or match either set. (Confused? Ask a librarian!)
• In most databases, put exact phrases in double quotes "like this." To search for various word endings, use an asterisk, e.g. painting* brings up results for painting or paintings.
