When researching, we are like detectives trying to combine the right terms in the right place to find the information we need. How should you combine search terms to find what you are looking for?
Search for information using the single most important term related to your topic. Use this type of search when looking for basic background information.
Search for information by combining key concepts using the words you have brainstormed. Each concept/word should be separated by the word "AND". Use this kind of search when looking for specific evidence related to your claim/thesis.
