Search Strategies

1. Divide topic into general concepts

Example: In the question, "How power plants affect the ecosystem in Pittsburgh?" the concepts are: ecosystem, power plants, and Pittsburgh. 


2. Think of synonyms and related terms
Example: Related terms of "power plant" can be "electricity generation" and "power station"


3. Use Boolean search method (search by combining your keywords using and, or, not)
  • Double quotes are used to combine words into a single search term.
  • The AND/OR/NOT keyword is used for logical AND/OR/NOT.
Example: "Ecosystem" AND "power plant"
