Identifying Keywords & Sample Searches
Your search strategy begins by identifying keywords and phrases that define your search topic. Write down these keywords and phrases; you will be typing them into our subscription databases to find scholarly journal articles on your topic. For the homework assignment in Experimental Design, keywords and phrases that will help you locate articles on experiments include:
- treatment or treatments

These terms can be used alone to retrieve the greatest number of articles on the topic or they can be combined with another subject term to narrow down your research topic. You can use the connector "AND" to combine subject terms and key phrases and keywords or just type your key phrases in the search box:
- experiment and subjects

Search terms can be very specific and include all disciplines:

Feel free to explore different possibilities by typing in different subject terms. There is no right or wrong term to use. Some articles will be exactly what you are looking for or you may find that some articles identify your search terms but are unrelated to your topic. If that happens, refine your search and select different keywords. If you are having difficulty formulating a search strategy please speak with an MCC reference librarian.
