NARROWING SEARCHES. 



Often when a search finds a large niunber of "hits" the questions 

 shown at the bottom of Figure 11 will appeeor. These questions should 

 normally be answered no by entering "n" and a Return/Enter. WETLANDS 

 has been designed to prevent the necessity for excessive use of these 

 options, but in some combined searches the options may provide a way 

 to narrow a search without starting over. 



If "y" is answered to the first question: 



DELETE A TERM OR PHRASE FROM TOUR SEARCH? > y 



the following second question will appears 



ENTER THE TERM OR PHASE TO BE DELETED > 



At this point, you would enter one of the codes displayed as a "hit" 

 at the top of the screen (not shown in this example). Then the 

 program continues the search, or returns you to the previous screen. 



If "n" is answered to the first question, the following question 

 appears t 



DO YOU WANT TO NARROW THIS SEARCH? > 



If "y" is answered, the following phrase will appear: 



|[) ALL TERMS WILL BE SEARCHED FOR IN THE LAST DOCUMENT SET CREATED 



This statement deletes the last item added to your search list. If 

 you are currently only searching one item, this will cause you to get 

 zero "hits," but it will not cancel the current search. This action 

 will preserve the search for use in a "List and Combine" operation, 

 however .
