Smart research: keywords and operators

A search engine is only as smart as the question you ask it. Smart research starts with the right keywords, sharpens with operators, and narrows down with filters. In one or two refinements you can turn a flood of unrelated pages into a small list of useful, trusted sources.

What this lesson teaches

1Pick precise keywords that name the main idea of a research question
2Use search operators to include, exclude, and lock exact phrases
3Apply site and filetype filters to limit results to trusted sources
4Refine a vague query into a sharper one and judge the new results
