Good literature searches begin with identifying your key concepts. Note the conceptual "chunks" in your topic, generate keywords and variations to use while searching, and decide how current or historical the articles should be. It may be possible to identify key researchers in the field then use them as search possibilities. Be flexible and prepared to modify your searching as you go.
An example of thinking in "chunks" -- "What type of foods do poor residents of Hunters Point have access to?"
o The geographical variations might include San Francisco or Bayview
o Foods could expand into "food desert," corner stores, farmers markets, etc.
o Poor resident adjectives might be "low-income," economically disadvantaged, etc.
