To build an effective search for a database it is best to use keywords instead of phrases.
A good strategy for building a keyword search is:
1. Develop a clear topic statement
2. Draw out the concepts from the topic statement
Main Concepts (Keywords) of Topic:
__________________________AND_________________________AND_______________________
|
3. Create a list of synonyms for each of the principal concepts
4.Conduct searches using the keywords and synonyms you have selected for a Boolean search (see window below)
5.Add more synonyms to your list as you encounter them in your research
