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, OR and NOT.
  In addition you can combine criteria using parenthesis to denote the
  grouping of the search criteria.

  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 | Telix | Procomm

Searches for any text having either PCBoard OR Telix OR Procomm anywhere in
the text


Multiple words searching for each word separately requiring ALL to match:
-------------------------------------------------------------------------
PCBoard & Telix & 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 | Telix)

Searches for any text having DESQview in it AND having either PCBoard OR Telix
also in the same text in any order and not necessarily together


Using the NOT operator:
-----------------------
