When thinking about your keywords, remember to:
Keywords : Words/terms that represent the main points/ideas of a topic - the most significant words in a topic, book or article. Used when searching databases and library catalogs as well as search engines on the Web.
Keyword searching finds words anywhere in the database record - in the title, subject headings, author's name, etc. Use the most important (or, "key") words in your topic, to get the most relevant results.
Identify Key Concepts
Write down your research question and circle or underline the words or terms that express the main idea/s.
Develop a List of Search Terms and Related Terms
Depending on the database, you may need to make your search more general or more specific.
Book titles are often quite general, and usually it is not possible to search the contents of the book. In the Library Catalog, search terms may need to be more general.
Journal and newspaper article titles tend to be much more specific, so in an article database, you might have to adjust your search and add more specific search terms.
OR - broadens a search by combining synonyms or alternative forms of words. Any of the words must be present. Write down any commonly used alternatives to/synonyms for your search terms and connect them with or
Example: cookery or cuisine or food
NOT - excludes terms from a search; narrows and focuses a search Example: dumpling not pierogi
TRUNCATION (aka wildcard) - symbol used at the end of a word or rootword to retrieve variant word endings, including plurals; makes a search more efficient by decreasing the number of searches. Example: immigra* retrieves: immigration, immigrant, immigrants, etc.
Many (not all) databases use the * as the truncation symbol. Check the online Help in each database to find which symbol is used.
Put the search together. Make your search more efficient by using the "and" "or" connectors in one search.
