Any meaningful word or phrase can be
searched in BIOSIS Previews, with or with-
out specifying the data elements to be
searched. Or, you can use data elements as
your key to a successful search. These data
elements can be searched in any combina-
tion to suit your needs. For example, if
your search focuses on a specific type of in-
formation such as Author or Journal Name,
you may want to limit specific search terms
to the particular data element containing
only that information. However, when
s e a rching a particular subject, it would be
wise to consider all the subject data ele-
ments in your sea rch, especially Ti t l e ,
