Indexing fails - empty body

TOPIC: Indexing fails - empty body

Indexing fails - empty body 01 Feb 2013 12:14 #965

Thanks - not complaining about the time just the fact that there was no response - I have sent you an email with the requested info and asked the hosting provider to enable Popen.

Hi,
in a first analysis, in your hosting server they are two problems:

1. popen (you have already reported to the hosting provider)
2. Unexecutable pdftotxt (we have tried to change permission but not works) permission must be given on some server providers.
You should make a new request to the "hosting provider" for:
a. put in "/libraries/ifile/adapter/helpers/binaries/linux/" the pdftotxt that your "server provider" uses in the server linux.
b. this pdftotxt must be executable

We now verify because the JiFile not read the filesystem folder configured in the options.

:) Decided to load the extension on the main server I use for production - not a normal thing to do as I like to test befor. However the product has worked on one PDF file so I do not think you need to progress the test server. I will now see if the product does what we require - thank you for your efforts.

Can you check out these PDF's please - the auto index says to check the encoding but I ddo not know how to do so. These are typical of some old documents I need to index.

Hi,
the first PDF "JournalisticJottings.pdf" is a OCR file created as an image.
JiFile uses XPDF, and this component not reads text from Image.
In fact if you try to select text from your PDF file, you can not copy text (see image).

This image is hidden for guests. Please log in or register to see it.


Your PDF is created how a image, you can scan your document using a OCR instrument, for create a PDF file in text form.
Warning!!!!, a PDF file, with OCR scan, could have problems when XPDF reads text (you could have loss of information).

The second PDF "TwoYoungScholars.pdf" works (see image).

This image is hidden for guests. Please log in or register to see it.


You must configured JiFile correctly.
The problem is the encoding of PDFs and the type of encodicg with which the contents are saved in index.

Let me explain better.
If you have a PDF wrote in UTF-8 Encoding, the XPDF must be configured for reading the content of PDF in UTF-8 (the default XPDF is configured for ISO-8859-1 Latin), and this is possible in "xpdfrc" file.

Now you must configured Lucene for indexing the content that the XPDF has read.
You must tell to Lucene that the content that must indexing is in UTF-8 encoding. This because Lucene, uses "iconv" function, for convert the content, the read content from XPDF, in encoding that has been configured in the "Analyzer Type".

In "Analyzer Type" it is recommended to always use "Utf8Num_CaseInsensitive" (this index test and number) or "Utf8_CaseInsensitive" (this index only text, if you search an number Lucene does not return results).

When you choose an "Analyzer Type", this should not be changed, otherwise you have problem in search terms.

Procedure:
1. open this file:
yourJoomlaRoot/libraries/ifile/adapter/helpers/binaries/xpdfrc/xpdfrc
the "xpdfrc" file not has extension, and not the must have.

- uncomment line 7 (delete # ):
textEncoding UTF-8

2. Set UTF-8 Encoding in JiFile configuration (see image).
