Background:
The Info-IBMPC Digest is a collection of Electronic messages covering
various topics related to the IBM PC family of personal computers.
The messages are collected and published twice a week (usually) and
distributed via various networks including the BitNet and ARPA
networks.
The InfoDoor program utilizes an Index file which contains one line
per message per issue of the digest. Each line of the index contains
the "Subject:" header for one message (just like the subject headers
for the messages on this board). It is this index file which is
searched for specified keywords and phrases.
When a match is found in the index file, the appropriate message(s)
are extracted and displayed.
Keyword Entry:
One or more keywords may be entered as the search criteria. The
syntax for keyword specification is as follows:
[token] keyword [token] [[token] [keyword] [token]] ...
"keyword" is a word or phrase to be matched in the index.
"token" is one or more of the following search string modifiers:
+ == logical AND (pat1+pat2 will match lines containing "pat1" and "pat2")
| == logical OR (pat1|pat2 will match any line containing "pat1" OR "pat2")
Searches will be performed without regard to case (eg. the keyword
"disk" will match all of "disk", "Disk", "DISK", "dIsk", etc.).
If both + and | tokens are found, the AND character will take
precedence in the search (eg. this+that|other will match on any
line that contains "this" followed anywhere by "that" and will also
match on any line containing "other".
Sample keyword entries:
disk|disc|hard disk - matches "disk" or "disc" or "hard disk"
disk+controller - matches a line containing "disk" and "controller"
