If you've found too many articles not exactly on your topic, there are ways to limit your results. Look at the database's search page and note the area titled "Limit the current search."

Expanded Academic allows you to limit your results:

• To articles with text
  Although this may seem the easiest way to get the full text of your article, it's probably not a good idea to begin a search this way, as it eliminates articles that may be exactly what you need but are in the library's print collection
• To refereed publications
  "Refereeing" or peer review is the process used to evaluate and accept articles for scholarly and academic journals, so this feature eliminates any articles from popular periodicals
• By date (of publication)
• To the following journal(s)
  Limits the search to the journals you specify (as long as they are indexed by Expanded Academic)
• To entries containing the words
  Further limit your search by adding words here that your results must contain
