A. Break your topic down into the main ideas, or keywords. Then combine your keywords into a search query:
Link main ideas together with AND to get fewer search results:
cookstove AND biofuel
Link related terms together with OR to get more search results:
biofuel OR biomass
B. Use quotation marks " " to search words as a phrase:
Searching “electronic control unit” excludes articles about metric units or electronic music.
BE AWARE – searching a phrase like “Grand Canyon National Park” in quotes excludes articles that just mention “Grand Canyon”

synth* = synthetic OR synthesis OR synthesize, etc
