Simplified Research Retrieval Tree (How to Plan a Search)

Step 1: Select the search tools you will use

(e.g. - Agricola, Academic Search Complete, JSTOR, Google Scholar, etc.)

⬇️

Step 2: Identify your primary topic keywords

(e.g. - salmon AND "water quality" and (standards OR parameters OR limits))

⬇️

Step 3: Identify any additional limits needed- region, species, data parameters, date, etc.

(e.g. - Pacific Northwest; Chinook, Coho; Nitrogen, Phosphorus, Dissolved Oxygen, etc.)

⬇️

Step 4: Include any needed access limitations

(e.g. - Interlibrary loan vs. full-text)

⬇️

Step 5: Read the abstracts to select the articles most likely to give you the greatest amount of useful information

Search Strategies

1. When searching the library catalog, databases, or the internet, AND / OR / NOT help you broaden or narrow your search results:

 

 

What Does It Do?
Search Examples
AND

narrows your search,
gets you fewer results


medical care AND ethnic*
finds information on medicial care that specifically pertains to ethnicity
OR


broadens your search,
gets you more results


steroids OR anabolic
finds information with the word steroids or information with the word anabolic
NOT


excludes certain terms,
gets you fewer results                              


steroid use NOT wrestling
finds information on steroid use, but excludes information about wrestling

 

2. Use truncation symbols (usually ? or *) in library catalogs and databases to capture all forms of words (ethnic* will retrieve ethnic and ethnicity).

3. Keep searches simple using keywords to capture core ideas. Search on ethics AND medical care AND immigrants rather than: Do immigrant communities receive an adequate standard of health care?

4. Use a variety of search words. (see: Identifying Search Words).  Try different searches to find different results:

  •  access to healthcare
  •  ethnic groups
  • immigrant communities
  • racism and medical care
  • self image women         

5. Become a power internet searcher!  Use advanced search techniques to get better results from your internet searches

Finding Background in Government Reports

You can skim reports and public news stories about local watersheds for measurable factors too!

example: Green River Watershed from King Co.
