Word stem search (= truncation)
Use the asterisk * to search for words with the same beginning.
Example: instead of migrating OR migration OR migrated… write migrat*, and you will search for all the variable endings of the word.
Phrase search
Example: ”phenotypic plasticity”
The quotation signs indicates two things:
1. You are searching for the two words together as a concept, not separately
2. You are searching for the words exactly as you have spelled them, all "extra help" is excluded (for example variant spellings and plural/singular)
Many search tools have a useful "Help section", and don't hesitate to ask the librarian for further help!
