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 ($) immediately after the last root character. 
like TI=AFRICA$. 
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$".
