Hi,

Thanks for sharing your thoughts on Zend_Search_Lucene.
I want to point to this:

…
# $doc->addField(Zend_Search_Lucene_Field::Keyword(‘id’, $i)); //Stores the ID
…

src: http://framework.zend.com/manual/en/zend.search.lucene.best-practice.html

Nevertheless it’s a good idea not to use ‘id’ and ’score’ names to avoid ambiguity in QueryHit properties names.

The Zend_Search_Lucene_Search_QueryHit id and score properties always refer to internal Lucene document id and hit score. If the indexed document has the same stored fields, you have to use the getDocument() method to access them.

@amin2u: Yes you have to put the .exe in the exe stmt. You can’t just copy the same code that I put out because that was optimzed for a unix install. You need to get the correct exe files from pdftotxt and use correct paths and exe’s

That’s correct. You need to download the .exe files form the site I posted above. If you downloaded the source that I included with the project you will just get the linux versions of the pdftotext.

admin2u: I would index your files with Zend and tag them with keywords. You can save each keyword in a document field for that pdf in the index.

As for XPDF on windows – go here http://www.foolabs.com/xpdf/download.html and download the win32 version. your php scripts will have to call it with a system_exec or exec functions, becuase you need to call the xpdf with a DOS command.

As for your error it looks like the error is in the fopen() function call. Make sure your path is correct.

Good luck!
