I’ve a lot of bagpipe writer music files, many are the same tune but a little different.

find -type f | egrep -i "bww$|bmw$" | wc -l
34565

Most contain information about composers, complete title, arrangements and information about harmony and seconds/thirds/whatever.

So I made a PHP search script and a BASH indexer.
(This is NOT a safe script to use servers with internet access)

PHP

Strict Search: <form method="post" action="?"><input type="Text" name="words" size=40 value=""><input type="Submit" name="submit" value="search"></form>
Fuzzy Search: <form method="post" action="?"><input type="Text" name="words2" size=40 value=""><input type="Submit" name="submit" value="search">Fuzzy-ness<input type="Text" name="words2key" size=1 value="3"></form>
Parsons Search: <form method="post" action="?"><input type="Text" name="words3" size=40 value=""><input type="Submit" name="submit" value="search">Fuzzy-ness<input type="Text" name="words2key" size=1 value="3"></form>

<P><PRE>
<?PHP
if ($_POST['words']) {
$words = preg_replace("(\r\n|\n|\r)", "", $_POST['words']); 
$words = preg_replace("/[^0-9a-z]/i",'', $words);
$command = "/bin/cat /var/www/html/findbww/bww.list |/bin/grep -i $words | sed 's/*\w\+//' | sed 's/\\/private\\/Private\\/Henri\\/save\\/move\\/cds-uitzoeken\\///g' ";
$blah=shell_exec($command);
$blah=str_replace("$words", "<b><font color=red>$words</font></b>",$blah);
print $blah;
}
if ($_POST['words2']) {
$words=$_POST['words2'];
$words2key=$_POST['words2key'];
$words = preg_replace("(\r\n|\n|\r)", "", $words); 
$words = preg_replace("/[^0-9a-z]/i",'', $words);
$command = "/bin/cat /var/www/html/findbww/bww.list |/usr/bin/agrep -$words2key -i $words | sed 's/*\w\+//' |  sed 's/\\/private\\/Private\\/Henri\\/save\\/move\\/cds-uitzoeken\\///g'";
$blah=shell_exec($command);
$blah=str_replace("$words", "<b><font color=red>$words</font></b>",$blah);
print $blah;
}
if ($_POST['words3']) {
$words=$_POST['words3'];
$words2key=$_POST['words2key'];
$words = preg_replace("(\r\n|\n|\r)", "", $words); 
$words = preg_replace("/[^0-9a-z]/i",'', $words);

Bash indexer (uses agrep)

#!/bin/bash
[ `find /FULLPATH/Music/Bagpipe-music-writer/ -type f  | wc -l` -eq 0 ] && exit
cd /var/www/html/findbww

locate -i bww |  egrep -i "\.bww$" |grep -v html.bww|  while read tunepath; do

Converting for parsons code.

Just place all files in a directory on a php enabled webserver.
The bash script is being run daily.
(parsons bash script is called from this main script)
These will generate 2 files
One with the filename and all useful text like composers.
And a file with the filename and the parsons code.
Example:
