Re-extract text (documents)

[Juergen]

Due to a server problem, we have some thousand pdf-documents uploaded, but the field id=72 (Extracted text) is not filled. This happened while uploading from different clients and a running staticsync with some thousand images and document. (Older pdf are fine)

I am not sure how to handle this with reindex.php. Is there a way to re-extract the text from the pdfs only?

I found this, but I am not sure, this is the right way: https://groups.google.com/forum/#!msg/resourcespace/cPTGszqFwZo/R14NI-ccVQgJ

Thanks for any advice.

You're going to want to use update_exiftool_field.php to re-extract the text before using a reindexing script.

You can pass the field you want to update by adding "&fieldrefs=72" to the end of the url.

You can also focus the script on a particular collection with "&col=<collectionID#>"

With thousands of documents on your list, you may want to try extracting from a few resources first to verify that pdf text extraction is working properly.

Allison,

thanks for this hint. When I try (collectionID = 44)

http://myrs.net/pages/tools/update_exiftool_field.php?fieldrefs=72&col=44

I get this output in the browser: "Please add an exiftool mapping to your Extracted text Field"

and none text is extracted. In the collection is one pdf only.

Kind regards,

Juergen

My mistake. With exiftool being so robust i often forget that it's not responsible for text extraction.

I don't think there's anything within RS that will do this for you. You may need to consider creating a small plugin that utilizes the function "extract_text".

Allison,

Don't mind - nevertheless, thank you for your time.
Actually I was a bit confused because of the exiftool. I thought maybe I missed a correlation.
Is this problem never occurred before? It concerns at least the basic functionality of RS.

Any idea is appreciated.

Kind regards,

Juergen
