b. Right truncated search terms
Instead of specifying a precise search
term, you may just give a root. This technique referred to as root searching
or right truncation allows you to search on leading sequences of characters.
CDS/ISIS will automatically perform a logical OR operation between all
search terms having the specified root. Please remember that in the queries
built by our system the terms are right truncated by default.
Right-truncation is indicated by placing
a dollar sign ($) immediately after the last root character.
As for precise search terms, if your root
contains parentheses, any one of the search operators, or begins with a
number sign (#) you must enclose it in double quotation marks ("), placing
$ before the final quatation mark e.g. or "TI=ARICA (south$".
