Examples of using boolean (and / or) searching
----------------------------------------------
There are numerous places where PCBoard will ask you for some kind of search
criteria for the text you want to scan. In those areas you can simply type
in a word or phrase or you may create much more complex searches by using
boolean logic symbols in your request.
The symbols "&" and "|" can be used to mean AND and OR respectively. In
addition you can combine criteria using parenthesis to denote the grouping of
the search.
The rules below apply at any prompt given where PCBoard wants you to tell it
what to scan for so the following rules can be used whether you are scanning
through the message base, the download directories, the users file or the
caller logs.
Multiple words making up a sentence or phrase:
----------------------------------------------
PCBoard version 14.5
Searches for the words "PCBoard version 14.5" all together in a line
Multiple words searching for each word separately:
--------------------------------------------------
PCBoard | Qmodem | Procomm
Searches for any text having either PCBoard OR Qmodem OR Procomm anywhere in
the text
Multiple words searching for each word separately requiring ALL to match:
-------------------------------------------------------------------------
PCBoard & Qmodem & Procomm
Searches for any text having ALL THREE words but not necessarily in any order
or even next to each other
Using parenthesis for grouping:
-------------------------------
DESQview & (PCBoard | Qmodem)
Searches for any text having DESQview in it AND having either PCBoard OR Qmodem
also in the same text in any order and not necessarily together
