The output looks okay. In the config file, if you set LIMIT_TO_DIRECTORY to false then does it index the PDF files?

Sorry for the delay in repsonding.

That helped by indexing a few of them but it did not inidex all of them.

Any other thoughts?

Try setting PHPDIG_IN_DOMAIN to true, LIMIT_TO_DIRECTORY to false, both in the config file, and then from the admin panel, use a large search depth, set links per to zero, and choose the no option. You can increase search depth beyond twenty by editing SPIDER_MAX_LIMIT in the config file. Once indexing completes, you should see an 'indexing complete' message onscreen. If, when indexing PDFs, the process seems to die in the middle, it might be a memory issue like in this thread.

Made those changes - back to square one. The indexing finishes but skips all the pdfs.

Beofre I made the last suggested config changes, the site was locked after indexinf a few of the PDFs and I had to stop the spider in the admin panel.

Try double checking that PHPDIG_IN_DOMAIN is set to true and LIMIT_TO_DIRECTORY is set to false. The latter should already be false from post two, but maybe it got switched back to true.

Also, in robot_functions.php find:
Code:
$command = PHPDIG_PARSE_PDF.' '.PHPDIG_OPTION_PDF.' '.$tempfile2;
And replace with:
Code:
$command = PHPDIG_PARSE_PDF.' '.PHPDIG_OPTION_PDF.' '.$tempfile2.' 2>&1';
Then try an index of PDFs and see what prints onscreen.

nothing else displays beneath but the top of the sreen indicates spidering is still in progress. admin panel says "locked" it did seem to find a few more PDFs but certainly not all

on the admin panel, i ask it to use a subdir of "policies". Under polices are 12 subdirs containing 1- 10 PDFs. All the PDFs are linked to the pages. From what rpintede on the screen it did not go down under policies despite using a search depth of 40.

Thanks

What is the filesize of the PDF file that appears after leadership.pdf in the list? It seems like there is a big PDF in there somewhere that is using up all your PHP memory, which in turn kills PhpDig so it stops indexing and remains locked. Look at the filesizes and unlink the big ones. PDFs of two or three MBs are probably okay, but it depends on your PHP memory.

Untested, but if you want to try and index part of the big PDFs...

In robot_functions.php find:
Code:
        while (!feof($fp)) {
            $file_content[] = fread($fp,8192);
        }
And replace with:
Code:
        $oh_stop_me = 0;
        while (!feof($fp) && $oh_stop_me < 125) {
            $file_content[] = fread($fp,8192);
            $oh_stop_me++;
        }
The 125 is meant to allow for 1,024,000 bytes from bigger PDF files.
