Example: (dinosaur OR (fossil AND paleo*))

If you choose to use a compound search term in a single search field, the search operators and their use depend on the Web Database being searched. For example, search terms for PubMed^® should follow the PubMed search criteria. The same rule applies for Web of Knowledge^SM products like Web of Science^®.

General guidelines for constructing search phrases are below.

• Parentheses () can be used to group search terms together.
• An asterisk (*) is used to search for a partial term.
• Double quotes (" ") will return references that contain the exact phrase quoted. Note: Not all sites support double quotes.

   

Note

Depending on the database source used for an Online Search, a space between terms may act as an AND operator returning references containing all the search phrases.
