Breaking down your research question or topic can help you figure out what search terms can be used to search through the library's catalog and databases. If your research question is "What are the impacts of different teaching styles on student performance and motivation?", the keywords you should start with are teaching styles, student performance, and student motivation.
Sometimes a book or article won't use the same words that you came up with. It is important to think of words similar to your original keywords that you may be able to use. You can use an online reference work to help you find other words or terms you can use. However, you won't use that as a source for your project as its not scholarly.
For example, some keywords one could use for "teaching styles" are:
"Teaching Strategies" "Teaching Methods" "Instructional Methods" "Educational Techniques"
A Boolean Search uses the operators AND, OR, and NOT to narrow, expand, or exclude results. Most databases allow you to use these words in the search bar, while some may require you to use the advanced search function. For example, Global Search requires you to put the Boolean Operators in ALL CAPS as shown below.
If you want to find a literature review on your topic, simply add "AND review" to your search terms. If you need a research study on the topic, add "AND study" instead.
