Creating your search
Break down your research question: We have to break down research questions because databases cannot break down sentences.
Example research question: How does the mineral composition of volcanic rock in Icelandic shield volcanoes differ from those in the Hawaiian shield volcanoes?
- Pick out the important word of your research question. These words provide the foundation of your search terms.
- Key Words and phrases: "mineral composition", "volcanic rock" volcanoes, "Icelandic shield", "Hawaiian shield"
- How else can you say your keywords and phases? Think of how you can become more broad and more narrow for some of your search terms.
- To make "Hawaiian shield volcanoes" more narrow I can search for specific volcanoes in the shield such as Mauna Loa, Mauna Kea, and Kohala.
- "Volcanic rock" can be rephrases as lava, magma, basalt, pumice, rhyolite, ect.
