After choosing a topic you need to determine what it is about that topic that you would like to know or to discuss. Set this up in the form of a statement or question.
When you have your statement/question ready, pick out the words relating to the main points – the “key” words. For example:
Topic: "Females have brought a positive element to the military."
Key words: "female" and “positive” and "military.”
Next, come up with related words for each key word in case any of the original key words don’t seem to be working out for the search. For example:
If any of your key ‘words’ are really a phrase, you’ll need to put quotation marks around them to tell the database that they must stay together in that arrangement. For example:
“World War II”
Use Advanced Search and put one key word in each box to keep them as individual terms.
Change out your search terms (key words/phrases) - mix and match - until you get some results you're satisfied with.
