Too many results
If you have retrieved too many results, think again about how to make your search more specific. Try using different keywords, add additional keywords, or limit your search to particular fields or publication years.
Too few results
If your search finds very little, try looking at the index or thesaurus of the database that you are using. This will help you to match keywords and spellings with those used in the database and may give suggestions for broader search terms.
