Search PDF's and return Match w/ PDF file link
I've been looking around and not too sure how to do this.
I have hundreds of PDF files that are inconsitent in format. I need to create a search engine that searches an entire pdf file thoroughly and other PDF files, returning matches along with a link to the PDF file.
Any particular modules I will need?
Actually if possible, I rather do this with Text Files. I can convert all my PDF's to textfiles if it makes things easier. I know I have Word Docs as well.
It is a lot of trouble installing new modules.
Thanks.
So far I have this which only reads a particular file and outputs it.
open (MYFILE, textfile.txt');
while (<MYFILE>) {
chomp;
print "$_\n";
}
close (MYFILE);

The great thing about Object Oriented code is that it can make small, simple problems look like large, complex ones

I already have a interface built on my own that searches against a database. I need to have it read a directory of pdfs to match results. I'm am very much a beginner at this. Any sample codes would help or direction.

Hmm...now I'm thinking about throwing the text file into an array and split by spacing or tab. I have tried both but they output the same. When I print [0] or [1], it grabs an entire sentence. I got to resolve this.
Anyways, even if I get that working the search will probably take a very long time. BUT, I have another idea. I want to add each letter's ascii code, add the entire word and have the script match the totals..THEN compare only the matched ascii totals, convert back to letters and match by word...this way it would speed things up..i hope.

That's not going to work. If you convert each character to ascii code and sum the codes there's no guarantee any two words won't have the same total. To the contrary, it's almost certain that a large number of different words will all sum to the same thing which will make the search massively inaccurate.

But wouldn't it cut down the next search alot?
I meant first search ascii then a second search with those ascii results but search them the normal way. Ok, if not this...any ideas?
I'm still having trouble splitting the contents by words in the file.
