A complete literature search can help you:
Considerations for establishing search criteria (may be helpful to answer these questions):
See AWIC full document for additional assistance and recommendations. These questions are available below as a word doc, if you wish to print and complete as a form.
Combine keywords using Boolean Operators (AND & OR)
Truncation broadens a search to retrieve items containing various forms of a word.
For example: model* could retrieve model, modelling, modeling, models etc.
Symbols used may be *, $, ?, or # (Database dependent ... PubMed uses * for right-hand truncation and Agricola uses * for either side).
Dangers in using truncation? Yes, shortening the word too much may retrieve too many results - for example, rat* could retrieve ration or rationing, while you are hoping to retrieve anything with Rattus).
Can specify words appear close together but further apart than an exact phrase
May use parentheses to group synonyms – watch for typos!!
Example: peer* adj2 (evaluat* or assess* or feedback or grad*)
