Refining Your Search (continued)
Another method of limiting your results is to search for your terms not as keywords, but in the titles of the articles. If your terms are contained in the article title, this pretty much ensures that the article will be relevant.
On the other hand, if you didn't find enough articles on your subject, you can use truncation to expand the number of results. Truncation allows you to create a root word and then add the truncation symbol (usually an asterisk or *) to stand in for any subsequent letters in the word. Taking one of our search words—immigrants—as an example, immigra* will also find articles containing the words immigrant, immigration and immigrating.
