Thanks for the tip. I do seem now to recall this method, but being a
python rookie and lacking the time to spend enough time with python to
drill it into my dreams....I'm bound to miss simple and basic things,
such as this.

Alot easier! Thanks.

Yes, IQ is a small search engine, stand alone but also a part of a larger
project.
The general difference with this search engine is that it follows the
generic triplet of how we define things for looking up later.
i.e. Unix manual pages can be tagged for 'word', 'sub' and 'file'
and can even use different 'filekeys' (legends like a map or blue print)
Look at the following AWK manual page. I've added keys here where ':'
tags for 'word', '::' tags for 'subs' and ':::' tags for file. The
CAPITALIZED words are original in the manual pages. But there is also
where I have added other keys for words, subs and files (in small case).
This further breaks down to more specific details of the awk man page, but
to use it, you need to change the 'filekey' to 'filekey :: ;; :::'
which allows you to access the finer details.
But Unix manual pages are one of many other expample of how we use this
triplet in defining and accessing information. Any Programming language
quick reference can be tagged or even non programming information like
catalog of parts or human language dictionaries or encylopedias, medical
references, etc..
Like I said, it's the "generic triple of how we define things to later
look up'. That's what the IQ search engine is about. And it's only one of
nine things we do in anything we do. Nine actions/functions that I call
"action constants". If you use the command line on the KNMVIC.iq file:
'>python IQ.py -k KNMVIC.iq "*" "*"
the result will appear to be a table of context of the KNMVIC document, so
even on a larger scale of perception, IQ is handy.
I hope all this help you to understand what the objective of IQ is. And
that if used to output specific parts, such as code, the '-s' option is
used to cause only the code or part to be output, without the
word/sub/filename key.
There is also the http://www.mindspring.com/~timrue/IQ.html file to read.

filekey : :: :::
:AWK(1) AWK(1)
::NAME
awk - pattern-directed scanning and processing language
::SYNOPSIS
awk [ -F fs ] [ -v var=value ] [ 'prog' | -f progfile ] [ file ... ]
::DESCRIPTION
Awk scans each input file for lines that match any of a
set of patterns specified literally in prog or in one or
more files specified as -f progfile. With each pattern
there can be an associated action that will be performed
when a line of a file matches the pattern. Each line is
matched against the pattern portion of every pattern-
action statement; the associated action is performed for
each matched pattern. The file name means the standard
input. Any file of the form var=value is treated as an
assignment, not a filename, and is executed at the time it
would have been opened if it were a filename. The option
-v followed by var=value is an assignment to be done
before prog is executed; any number of -v options may be
present. The -F fs option defines the input field separa
tor to be the regular expression fs.
An input line is normally made up of fields separated by
white space. (This default can be changed by using the FS
built-in variable or the -F fs option.) The fields are
denoted $1, $2, ..., while $0 refers to the entire line.
A pattern-action statement has the form
pattern { action }
A missing { action } means print the line; a missing pat
tern always matches. Pattern-action statements are sepa
rated by newlines or semicolons.
::statements
An action is a sequence of statements. A statement can be
one of the following:
if( expression ) statement [ else statement ]
while( expression ) statement
for( expression ; expression ; expression ) statement
for( var in array ) statement
do statement while( expression )
break
continue
{ [ statement ... ] }
expression # commonly var = expression
print [ expression-list ] [ > expression ]
printf format [ , expression-list ] [ > expression ]
return [ expression ]
next # skip remaining patterns on this input line
delete array[ expression ]# delete an array element
exit [ expression ] # exit immediately; status is expression
Statements are terminated by semicolons, newlines or right
braces. An empty expression-list stands for $0. String
constants are quoted " ", with the usual C escapes recog
nized within. Expressions take on string or numeric val
ues as appropriate, and are built using the operators + -
* / % ^ (exponentiation), and concatenation (indicated by
a blank). The operators ! ++ -- += -= *= /= %= ^= > >= <
<= == != ?: are also available in expressions. Variables
may be scalars, array elements (denoted x[i]) or fields.
Variables are initialized to the null string. Array sub
scripts may be any string, not necessarily numeric; this
allows for a form of associative memory. Multiple sub
scripts such as [i,j,k] are permitted; the constituents
are concatenated, separated by the value of SUBSEP.
The print statement prints its arguments on the standard
output (or on a file if >file or >>file is present or on a
pipe if |cmd is present), separated by the current output
field separator, and terminated by the output record sepa
rator. file and cmd may be literal names or parenthesized
expressions; identical string values in different state
ments denote the same open file. The printf statement
formats its expression list according to the format (see
printf(3)). The built-in function close(expr) closes the
file or pipe expr.
::math
The mathematical functions exp, log, sqrt, sin, cos, and
atan2 are built in. Other built-in functions:
::built-ins
;;length
length the length of its argument taken as a string, or of
$0 if no argument.
;;rand
rand random number on (0,1)
;;srand
srand sets seed for rand and returns the previous seed.
;;int
int truncates to an integer value
;;substr
substr(s, m, n)
the n-character substring of s that begins at posi
tion m counted from 1.
;;index
index(s, t)
the position in s where the string t occurs, or 0
if it does not.
;;match
match(s, r)
the position in s where the regular expression r
occurs, or 0 if it does not. The variables RSTART
and RLENGTH are set to the position and length of
the matched string.
;;split
split(s, a, fs)
splits the string s into array elements a[1], a[2],
..., a[n], and returns n. The separation is done
with the regular expression fs or with the field
separator FS if fs is not given.
;;sub
sub(r, t, s)
substitutes t for the first occurrence of the regu
lar expression r in the string s. If s is not
given, $0 is used.
;gsub
gsub same as sub except that all occurrences of the reg
ular expression are replaced; sub and gsub return
the number of replacements.
;;sprintf
sprintf(fmt, expr, ... )
the string resulting from formatting expr ...
according to the printf(3) format fmt
;;system
system(cmd)
executes cmd and returns its exit status
The ``function'' getline sets $0 to the next input record
from the current input file; getline <file sets $0 to the
next record from file. getline x sets variable x instead.
Finally, cmd | getline pipes the output of cmd into get
line; each call of getline returns the next line of output
from cmd. In all cases, getline returns 1 for a success
ful input, 0 for end of file, and -1 for an error.
::patten matching
Patterns are arbitrary Boolean combinations (with ! || &&)
of regular expressions and relational expressions. Regu
lar expressions are as in egrep; see grep(1). Isolated
regular expressions in a pattern apply to the entire line.
Regular expressions may also occur in relational expres
sions, using the operators ~ and !~. /re/ is a constant
regular expression; any string (constant or variable) may
be used as a regular expression, except in the position of
an isolated regular expression in a pattern.
A pattern may consist of two patterns separated by a
comma; in this case, the action is performed for all lines
from an occurrence of the first pattern though an occur
rence of the second.
A relational expression is one of the following:
expression matchop regular-expression
expression relop expression
expression in array-name
(expr,expr,...) in array-name
where a relop is any of the six relational operators in C,
and a matchop is either ~ (matches) or !~ (does not
match). A conditional is an arithmetic expression, a
relational expression, or a Boolean combination of these.
The special patterns BEGIN and END may be used to capture
control before the first input line is read and after the
last. BEGIN and END do not combine with other patterns.
::variables
Variable names with special meanings:
FS regular expression used to separate fields; also
settable by option -Ffs.
NF number of fields in the current record
NR ordinal number of the current record
FNR ordinal number of the current record in the current
file
FILENAME
the name of the current input file
RS input record separator (default newline)
OFS output field separator (default blank)
ORS output record separator (default newline)
OFMT output format for numbers (default %.6g)
SUBSEP separates multiple subscripts (default 034)
ARGC argument count, assignable
ARGV argument array, assignable; non-null members are
taken as filenames
ENVIRON
array of environment variables; subscripts are
names.
Functions may be defined (at the position of a pattern-
action statement) thus:
function foo(a, b, c) { ...; return x }
Parameters are passed by value if scalar and by reference
if array name; functions may be called recursively.
Parameters are local to the function; all other variables
are global. Thus local variables may be created by pro
viding excess parameters in the function definition.
::EXAMPLES
length > 72
Print lines longer than 72 characters.
{ print $2, $1 }
Print first two fields in opposite order.
BEGIN { FS = ",[ \t]*|[ \t]+" }
{ print $2, $1 }
Same, with input fields separated by comma and/or
blanks and tabs.
{ s += $1 }
END { print "sum is", s, " average is", s/NR }
Add up first column, print sum and average.
/start/, /stop/
Print all lines between start/stop pairs.
BEGIN { # Simulate echo(1)
for (i = 1; i < ARGC; i++) printf "%s ", ARGV[i]
printf "\n"
exit }

gramming Language, Addison-Wesley, 1988.

::BUGS
There are no explicit conversions between numbers and
strings. To force an expression to be treated as a number
add 0 to it; to force it to be treated as a string con
catenate "" to it.
The scope rules for variables in functions are a botch;
the syntax is worse.
