You need converters from the media format (i.e. PDF, MS-Word, ...) to text (or maybe better named: text extraction utilities). The standard PDF converter is "XPDF" (which contains "pdftotext" (or similarly)). The standard Word converter is "wvware". -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Indexing files
when you say external PDF converter, do you mean the pdf converter I created the pdf file with? I have tried to index a microsoft word file also, but the result is the same: an empty index. - Sune > > > --On 24.

Re: [Zope] Indexing files
Hei again. I have installed TextIndexNG and indexed my Zope DTML Methods objects and Zope Files objects, and enabled "Document converters (PDF, Word etc.)" As indexed attributes I use SearchableText,PrincipiaSearchSource,getFile, but the indexes related to the pdf files are still empty. Is it correct to upload my pdf document as a Zope File object?

Newer Zopes have file-objects indexable via PrincipiaSearchSource
if their content-type is text/*
OFS/Image.py, 423ff:
def PrincipiaSearchSource(self):
""" Allow file objects to be searched.
"""
if self.content_type.startswith('text/'):
return str(self.data)
return ''
