Be elastic & be specific. Both are necessary. Research is a fluid, creative and elastic process. For example, you can narrow down your topic when it is too broad or when you find too much information. Using specific words can make your search results more precise. You can expand, refine, and revise your search words when you do not find enough information or the right information. Always, pay attention to new keywords and subject words that you will discover in the book or article citation/description. Add them to your notes. You may be surprised that your essay will miraculously grow from your words, thoughts, and notes over time.
