Hi,

I’m just trying to test your Code but I have a problem with xpdf .
I’m not sure to do it well. I downloaded the win 32 version of xpdf and copied the folder in my document path but’it doesn’t work.

$pdf_filename = “celia”;
// get pdf information
$output = shell_exec (“pdfinfo “.$pdf_filename.”.pdf”);
//Gets the metadata
$data = explode(“\n”, $output); //puts it into an array

//Gets the metadata
$data = explode(“\n”, $output); //puts it into an array
print_r($data);

print_r($data) returns nothing.

Can you help me please?

@ZEMZEMI – I’m not sure if XPDF gets the metadata or not. if it does you can just store them in the index. and retrieve them when you loop through the hits.

Hi,
Thanks you for your source code, It was very helpful for me. But, I have some questions : did XPDF retrieve Keywords Metadata ? I don’t think so because I tested your code with XPDF library and it shows authors, title, date…
I want to konw if I can retrieve keywords with zend_search_lucene.

thanks

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
