This page will assist you with locating research resources within scholarly databases (e.g. databases with peer-reviewed research). There are a few steps that you will need to utilize. They are all detailed on this page. Please let me know if you have any questions.
For example, let's say we're interested in exploring either of these two topics:
Topic one: “Changes in grape composition after the harvest, before processing”
Topic two: “Quality of a fruit or vegetable as a function of maturity”
How do we turn that topic idea into usable research?
Remember:
Step 1: What words will you put into the database search?
My first task is to pull the keywords that I want to search out of this statement (if we just search the entire statement we'll get a bunch of useless results). I really just want to pull out my variables (e.g. what do I want to study?).
So, what do I want to study:
Topic One: “Changes in grape composition after the harvest, before processing”
What I want to study is: Grapes, change in composition, post-harvest (but before processing)
Topic two: “Quality of a fruit or vegetable as a function of maturity”
What I want to study is: Fruit or vegetable, its quality, as a function maturity
Step 2: Are there synonyms, plurals, and other concepts we should also search?
Remember:
Our keywords could (potentially) be:
Topic One: “Changes in grape composition after the harvest, before processing”
Keywords: grapes. grapevine, changes, differences, developments, post-harvest, after harvest, post harvest, before processing, pre-processing, preprocessing
Topic two: “Quality of a fruit or vegetable as a function of maturity”
Keywords: Quality, aspects, traits, fruit, vegetables, maturity (if we wanted we could also add some specific fruits and vegetable names)
Remember:
Step 3: Let's create a search string (so we don't have to do multiple searches)
See box below for info regarding creating search strings and utilizing Boolean Operators.
Most databases will have a drop-down menu that lists three Boolean Operators, AND, OR, NOT.
These Boolean Operators will allow you to create quick and powerful search statements.
Remember:
Boolean Operators Table
OR Search example: grape OR vitis OR muscadine
|
One or both of these terms will be in your search results. OR will give us the potential for more results. | The operator OR is particularly helpful when you want to broaden your search, especially when you want to include synonyms. |
AND Search example: grape OR vitis OR muscadine AND "post harvest"
|
Now our search results must have either grape or Vitis in the search results as well as post harvest AND will give us less results but it will make our results more useful. |
AND is how you are going to search multiple concepts/variables together. |
NOT Search example: Fruit NOT apples
|
Narrows search results. This search would return all the results that have fruit but not apples. | NOT is used to eliminate records. |
Other Database Tools
Quotation Marks (" ") Search example: “Washington State” Would return the result: The history of Washington State University Would not return the result: The history of Washington D.C. and Maryland. |
Only returns results utilizing that exact phrase as it appears in the quotation marks. |
The Wildcard (*) Search example: grape* Returns results:
Returns results:
S*food* Returns results: |
The * can be used anywhere in the search term to represent any characters (or no characters). It is a super easy way to conduct searches that pertain to all of the variations of a term. |
Step 4: Write your search statement:
My search statement will look something like:
Topic one: “Changes in grape composition after the harvest, before processing”
Search String (could include):
grape* OR vitis OR muscadine OR muscat
AND
change* OR difference* OR development*
AND
"post-harvest" OR "after harvest" OR "post harvest" OR "before process*" OR "pre-process*" OR "pre process*"
This will find all of the results for: Grape, grapes, grapevine, grapevines, Vitis, Muscadine, change, changes, changed, difference, differences, development, developments, developmental. post harvest, post harvesting, post harvests, pre processed, pre processing, preprocessed, preprocessing, pre-processed, pre-processing, before harvest, before harvesting, before harvests, etc.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Topic two: “Quality of a fruit or vegetable as a function of maturity”
Search String:
qualit* OR aspect* OR trait*
AND
fruit* OR vegetable*
AND
matur*
This will find all of the results for: Quality, qualities, aspect, aspects, trait, traits, fruit, fruits, vegetable, vegetables, mature, maturation, matured. maturing, etc.
