Final answer:
To search with unknown terms on a search engine, use a wildcard character. Learning Boolean Operators like AND, OR, and NOT refines the search. Keywords are crucial in finding credible sources and should be noted during research.
Step-by-step explanation:
When using a search engine and needing to search with unknown terms, a wildcard can be used. This special character can substitute for any number of characters and help in broadening the search results. Search engines often use mathematical procedural rules to determine the relevance of web pages, which do not always prioritize the most credible or accurate information.
To refine search results, it is important to become familiar with Boolean Operators like AND, OR, and NOT. These operators help to either narrow down the search by including all terms (using AND), widen it by allowing for either term (using OR), or exclude certain terms (using NOT). For instance, searching for "artificial intelligence" AND "robotics" will provide results that contain both terms.
Furthermore, keywords play a significant role in effective search strategies. Using the right keywords is essential for locating credible sources. It's beneficial to note down different terms related to your topic as you research, as this will help in both keyword and subject searches throughout your research process.
