Transcript of "How to construct a search for BIO1000H students"

  1. 1. How to construct a search This work is licensed under a Creative Commons Attribution- NonCommercial-ShareAlike 3.0 Unported License.
  2. 2. SEARCHING DATABASES Mendel’s influence on the discipline of genetics CONCEPT 1 1. Write down your topic in its simplest form Then break it up into CONCEPTS. CONCEPT 2
  3. 3. Mendel’s influence on the discipline of genetics CONCEPT 2 CONCEPT 1 2. Think of other similar SEARCH TERMS that describe each of your concepts : CONCEPT 1 Gregor Mendel CONCEPT 2 genes
  4. 4. 3. Construct your search strategy  Boolean logic provides the language you use to structure your keyword search … the search engine needs to know how your search terms relate to each other  In Boolean searching, you make use of the three Boolean operators: AND OR NOT
  5. 5. Use AND to combine different concepts : Genetics AND Mendel • The results of your search will contain both words i.e. Mendel and genetics. • AND narrows your search results, as it retrieves only those articles that have both search terms • The green shaded area in the illustration represents the result of your search. AND =
  6. 6. Use OR to enter keywords for the same (single) concept : genetics OR gene • The results of your search will contain either genetics or genes. • OR broadens your search results, as it retrieves any one of your search terms. • The yellow shaded area in the illustration represents the result of your search. OR =
  7. 7. Use NOT to get rid of unwanted results : genes NOT genomes • The results of your search will NOT contain the word ‘genomes’ • The blue shaded area in the illustration represents the result of your search. =NOT
  8. 8. Mendel OR “Gregor Mendel” Genetics OR genes AND CONCEPT 1 Mendel Gregor Mendel CONCEPT 2 Genetics Genes Mendel’s influence on the discipline of genetics Search tip: Use “…..” when you want to search for words that must be found next to each other
  9. 9. ONE SEARCH BOX: Use brackets to separate your concepts STRUCTURED SCREEN: Mendel OR “Gregor Mendel” Genetics OR genes (Mendel OR “Gregor Mendel”) AND (genetics OR genes) 4. Type your search strategy into the database search screen
