I purchased this program and it is not ready for prime time.
The install went simply as do most Joomla components. The initial indexing of 100 pdf files proved to be a resource hog as it send warning bells and whistles to my isp. PDF Indexer used over 20% of cpu resources.
My account was immediatley shut down by a linux script and I had to call my ISP to have my account reinstated. They told me that it was most likely caused by poorly written code and it is rare they have many problems with Joomla (which they advertise).
After the initial indexing the program will skip the previously indexed files and just index new files added. I would suggest that you index maybe 10 files at a time.
I informed the author and I think he may be looking into this. It would probably be easy to add some sort of timer when indexing that allows 5 files to be indexed every minute or so. If you have your own server this will not be an issue, but for those of us that are on shared systems we will get hammered by our isp's. Like I said this should be a simple fix adding a couple of lines of code.
The second issue I have is that most of my pdf files were created by Adobe acrobat 7. This caused pdf indexer to not work properly and gave errors on every file created with acrobat 7 (uses AES encryption - version 1.6 pdf files).
The reason behind this is because pdf indexer uses the program xpdf for its pdf to text conversion and then dumps the converted text into your database.
It is a widely known issue that xpdf is not capable of reading version 1.6 pdf files at this point in time. Therefore there were errors with every pdf ver 1.6 file. It works fine with ver 1.5 and below.
If I would have known all this up front I would have not purchased the program in its current state.
Once you get past these problems on the backend, the frontend appears to work well in that the pdf's that did index showed up properly in a search.
I feel that the author is not very responsive to these issues for charging for a product that only half works.
This can be a great product, but it relies on an outdated engine (xpdf). The author should let folks know this up front before they purchase.
Owner's reply:
"PDF Indexer used over 20% of cpu resources."
This is the first report of this I have seen.
"It is a widely known issue that xpdf is not capable of reading version 1.6 pdf files"
It does read and index the files. There is just a warning at the beginning of the index.
I responded to this user within 1 hour of his complaint and then never heard from him again.
