Wildcards

Wildcards allow you to construct a query with approximate search terms. Use a question mark (?) in a search term to represent any one character and use an asterisk (*) to represent zero or more characters. There are two limitations of wildcards: (1) they cannot be used at the beginning of a search term and (2) they cannot be used in a phrase enclosed in quotation marks.

Stemming

You can expand your search by enabling stemming. Simply check the checkbox that appears just before the Journal Titles heading in your Search Criteria. [Show me the stemming option in the Search Criteria]

Enabling stemming will automatically include the root terms of the words you have used in your search. For example, if you have stemming enabled and are searching for the word "nanotubes", your search will also include results from the singular form of the word "nanotube", as well as other words using the root term "nano" such as "nanoscience", "nanoscale", etc.
