Which of these search methods is best when you are using literature references to find other relevant publications about your subject?
1. the snowball method: this is the most frequently used method for finding relevant publications.
How can you define your subject precisely?
3. By specifying a period in years. All the other answers refer to actions that would do the opposite, i.e. broaden your subject.
How can you combine different search terms to form a phrase/concept?
The two correct answers are 1 (use AND) and 3 (use “.....”).
In some cases, the other option is to put the words in a single search box.
The options will depend on the database you are using, so it's a good idea to check using the Help function.
