Description:
On servers which don't admit server-side scripts
(PHP/ASP/etc..) if you wish to add a search engine you have 2
options:
-To use a dedicated external engine.
-Or to use a script that runs on client side.
The second option has the advantage that you can use the search
engine offline (on html help, tutorials, etc..).
JavaScripts cannot search through directories on the server, so
you must make a file which contains a database with the words
you like to be searched for.
I made a console program (JavaScript Indexer) which scans a specified
directory and all subdirectories for "*.htm*" and "*.txt" files
and automatically indexes the web site, creating a database on
a js file.
It writes the search function into the same file. So all you have
to do is to add few lines to the web page and you have your search
engine running. These lines are:
Add this line in the HEAD section of the html (just after <HEAD>):
You can paste this code into your page. The ".js" file is the
file created by the program. This file must be added on server.
Sample:
You can test it on my page. Type a common word on the input
box on the top of the page and click the Search! button or press
Enter. To see multiframe example click here. For a sitemap generated from database click
here.
Requirements and compatibility:
Microsoft Windows 9x, NT, Me, 2000, XP for jsind.exe
The script theoretically works with these browsers:
Internet Explorer 4 to 6
Netscape Navigator 4 to 7
But the the reality is different. It was tested with these browsers:

Performance:
The main drawback is that the program is slow with big files.
A 150k file containing a big table is processed in up to 20
seconds. In return the script runs faster with fewer big files.
A database of 550 pages and 3.5MB is searched in approx. 40-60
seconds. An average web site is searched in maximum 5-10 seconds.
For small sites (smaller then 25 pages) and low speed connections
this engine is faster then a PHP/ASP version because the database
is loaded with the page and the engine generates the result
on the client browser. The search speed is processor power dependent.
The information above is obtained on my old AMD K6-2@500MHz.
On a faster PC the search speed is greater.
Customization:
You can customize the look of the generated result page by editing
the default.inc which comes with the program or by creating
another inc file and by editing the jsind.ini.
