Web of Science Goes With Google

ISI have made a fundamental change to the way that Web of Knowledge (including Web of Science) databases search.

When using the Topic Search or Quick Search options, search terms are no longer automatically "phrase" searched, they are instead automatically "anded".
This is similar to the way that the Google search engines operate. If you enter a phrase it now searches for records containing all of the words in the phrase rather than only for those containing the phrase itself - quotation marks are necessary to force an exact phrase search.

For example, instead of entering fire blight AND zealand
you should now enter "fire blight" zealand

However if you wish to use OR to allow a choice of keywords it is necessary to enclose the ORed terms in brackets and to use AND -

"fire blight" AND (zealand or australia)


For more information see the help screens on Web of Knowledge, or contact your Liaison Librarian.
