Library databases are different than Google, and require specialized search techniques. Use these strategies in library databases to retrieve better results more efficiently.
These strategies can be used in most library databases as well as the library catalog.
Boolean operators are the connectors AND, OR, NOT. Combine keywords using Boolean operators in order to create the most effective search strategy.
AND will narrow your results: Ex. Searching for "gun control laws AND crime rates" will retrieve only items where both terms are present.
OR will broaden your results: Ex. Searching for "law OR legislation" will retrieve items where either term is present.
NOT will exclude terms from your results: Ex. Searching for "gun control laws NOT Australia" will retrieve items where the first term is present but exclude results that contain the second term.

Sometimes this can be a very effective way to search. Other times you might find that you are getting results that seem off-topic or you are getting too many results. This is when subject searching can be helpful.
