First, try a simple keyword search such as Abortion. Keyword searches produce a large amount of results. This type of search is broad and less precise. Fortunately, most online catalogs and databases have features to help you refine your search terms. Refinement features may include author, year, format, content, audience, or sub-topics.
Creating a search strategy:
Next, try Boolean searching. This type of searching allows you to combine keywords using operators AND, OR, and NOT.
To narrow your results use AND with two or more concepts. Example: Pro-Life and Adoption. Results will include both terms.
To broaden your search use OR with synonymous or related words or phrases. Example: "Pro-Life" Or "Anti-abortion" - This type of search expands the search so that you have one result or both.
Sometimes one of your search terms may produce a list of results that includes articles that are not relevant to your topic. Using the operator NOT eliminates words from your search and reduces the number of results. Example: Abortion and Ethics NOT legislation. The word legislation will be excluded from the search.
