Final answer:
To improve information search using keyword search, choose specific key terms related to your topic, practice generating key terms, take note of the variety of terms that describe your research area, and use Boolean operators (AND, OR, and NOT) to focus your search.
Step-by-step explanation:
When searching for information through keyword search, it is important to choose specific key terms related to your topic. Libraries and online databases generate search results based on algorithms that target keywords. Academic libraries use Library of Congress Subject Headings (LCSH) for subject searches, while online sources use algorithms unique to that database. To improve your search results, practice generating key terms and take note of the variety of terms that describe your research area. Additionally, familiarize yourself with Boolean operators (AND, OR, and NOT) to focus your search and link necessary information.
