Tika Server: Disable OCR / Tesseract by HTTP parameter?

Hello,


is it possible to optional disable OCR (by Tesseract) in Tika Server by 
a HTTP / HEADER / POST / GET / REST-API parameter (i.e. for some but not 
all documents) instead of disable it global in tika.xml config or 
uninstall Tesseract like in the documentation 
https://wiki.apache.org/tika/TikaOCR ?


Best regards,

Markus

thank you very much!

I had not expected the path config parameter is setable by HTTP header.

It works (if i use HTTP PUT for upload the file).

If i use(d) HTTP POST (which in Tika documentation can be used too and 
works for analysis with default config of Tika Server) to upload the 
file, settings in HTTP HEADER don't work (like the setting of the OCR 
dictionary).

But this is maybe not a problem in Tika but could be a problem of my 
pycurl parameters.

Others may be more familiar with tika-server and OCR, but I notice that we do process X-Tika-OCR prefixed headers to configure TesseractOCRConfig .  If you set "tesseractPath" to something bogus, that may turn off OCR...give something like this a try:

--header "X-Tika-OCRTesseractPath:/bogosity"
