          Components: ocr
    Affects Versions: 1.18
            Reporter: Markus Mandalka


Tika 1.18 fails with returned status 500 if setting MULTIPLE (delimited by +) dictionaries for Tesseract OCR set by HTTP {{header like "X-Tika-OCRLanguage: eng+fra"}}

Setting a single OCR dictionary works.

Relevant documentation part from https://wiki.apache.org/tika/TikaOCR:
h2. Overriding the configured language as part of your request

Different requests may need processing using different language models. These can be specified for specific requests using the _X-Tika-OCRLanguage_ custom header. An example of this is shown below: 

{{curl -T /path/to/tiff/image.jpg http://localhost:9998/tika --header "X-Tika-OCRLanguage: eng"}} 

Or for multiple languages: 

{{curl -T /path/to/tiff/image.jpg http://localhost:9998/tika --header "X-Tika-OCRLanguage: eng+fra"}}
