1. Note single words or short phrases
-
You will not use complete sentences to search.
-
Leave out minor words such as ("a," "an," or "the") and prepositions or verb phrases ("on," "in," or "going to").
-
Use nouns (person, place, or thing) as keywords.
-
Avoid verbs (action words) and adjectives (descriptive words).
2. Play with synonyms
For example: start with the word "trash," then try using the words "garbage" or “waste.”
3. Think of related terms to describe your topic
For example, related terms to "pollution" are "acid rain," "global warming," or "refuse water." The related terms may be more specific or less specific than your original term.
