A year or two back I needed a search script to scan thru HTML files
on a client site. Usual sorta thing. A quick search turned up a
neat script that provided great search results. It was fast,
returned the hyperlinked page title, filename, and the body txt (30
preceding and following words) in context with the search word
highlighted. Excellent.!
See it working at: http://www.ipt.co.za
Just search for "firearm"
I now need to use it on a different site but I've run into two
limitations which made it unsuitable. It will only search the root
folder of a domain and won't cascade the search down through sub-
folders. Hmmmm. Pity. Checked the code but couldn't modify it
successfully. Aah well, look elsewhere.....
After hours and hours of scouring through the script sites I began to
realise what a lucky find that original script was. Almost
everything new that seemed promising either had major limitations,
presented poor results or just would not work properly. And, most
importantly, none of them offered that *excellent* feature where the
search term was displayed embedded in the context.
I now believe that this is a great script that needs two
modifications:
1. The ability to be pointed to a sub-folder of a domain as the
starting point for the search. But, as a compromise, this could also
be achieved as the folder in which the script itself is lying.
2. The ability for the search to cascade on through sub-folders
lying below the folder in which the search is initiated.
It would also be great if the original casing for the page title and
context could be preserved but that really isn't a critical issue.
Maybe one could even specify the file extensions for searching to
speed things up. Suggestions would be greatfully received.!
Please can somebody out there help with some ideas as to where this
script can be modified to provide these functions. I'm sure this
would an excellent resource for the ASP community and it certainly
fits my requirements.
Here's hoping ...... code follows below.!
TIA
