Use the AND connector to find words that are far apart from one another or in different sections. As a general rule, use AND when it doesn't matter where your search words appear in a document.
If your search terms are fairly unique, the AND connector can find documents that are related to your research. Using the AND connector can also help you get started on your research, until you begin to find more specific concepts and terms for your search. For example, if you would like information about natural justice and fair hearing, you could use this search:
natural justice AND fair hearing
