Re: [fw-mvc] Zend_Search_Lucene and PDF files

Bill, I have looked at the Zend_PDF and I am not sure you can read the text.  I will look again in 1.9.2 and see.  I think its write only. But I could be totally wrong.  It may be a good question to ask in the #PHPC chat room

Thanks Shaun and Matthias,

Shaun: I actually already found your post, and so far it is the most likely scenario if I cannot get a pure PHP solution working - The server is OpenBSD, but development is done on OSX, Linux, and Windows so it presents a problem with the XPDF.  But if push comes to shove it's where I will be heading.

Matthias:  It needs to be able to update on the fly, and running Java up there may be a bit dicey...  There is also a db component, so some of the meta data comes from my model, and well - its seeming to look painful as I move ahead either way - thanks for the suggestion though!

I was really hoping someone with Zend_PDF knowledge would see this and yell, hey - just grab this array from the PDF object, its got your strings :)

Thanks guys!

About a 1 1/2 yrs ago I wrote a 2 part post on how to index pdf's with Zend. (http://www.kapustabrothers.com/2008/01/20/indexing-pdf-documents-with-zend_search_lucene/)  the Framework has come along way since then so it's probably out of date. I have been thinking about updating the topic.  The current implementation uses XPDF which at the time was the best to convert PDF's to Text.  I have been looking for some other libraries but have no luck.  I'm also looking so ill let you know if i find anything.

Hi,
some time ago I had the same problem. But I needed the support for other
documents, too (Excel, Powerpoint, ...).
Because of this I created my index with java Apache projects: Lucene, PDFBox
(PDF parser/writer) and POI (Office document parser/writer).

I think it wouldn't be much work to parse your PDF docs Java-side...
