Description

Currently to change the language for tesseract I have to manipulate the \org\apache\tika\parser\ocr\TesseractOCRConfig.properties in tika-parsers-1.16.jar.

There is no possibility to set the language in solrconfig.xml or on each request to the ExtractingRequestHandler.

If someone has documents with different languages its impossible to configure this. Tesseract will not work as good as it could with correct set language.
