------------------------------------------------------------------
The format of the configuration file is not well described (yes, I agree,
writing a documentation is boring :)), that's why I'm working from assumptions.
Assumption 1: <mime-exclude> and <parser-exclude> belonging to one
parent-element are independent
Assumption 2: <parser> elements are independent too.
So, if the assumptions above are true, then I do not understand, why the second
<parser> definition (for PDFParser) does use the settings (exclude
TesseractParser) from the first <parser> element (DefaultParser).
I'm hoping, the guy who wrote the code would read the ticket and could clarify
the behavior and could shed a light on how to enable OCR for PDF only. Thanks!
P.S. OCR working fine without the config above: "extractInlineImages true" in
PDFParser.properties and "tesseractPath=/path/to/tesseract.exe" in
TesseractOCRConfig.properties are set.

> Key: TIKA-1963
> URL: https://issues.apache.org/jira/browse/TIKA-1963
> Project: Tika
> Issue Type: Bug
> Components: config
> Affects Versions: 1.12
> Environment: windows, java version "1.8.0_73", 64 bit
> Reporter: Konstantin Avdeev
>
> Hi everybody!
> I'm trying to white-list a particular mime-type for OCR with the following
> config:
> {code}
> <properties>
> <parsers>
> <parser class="org.apache.tika.parser.DefaultParser">
> <mime-exclude>application/pdf</mime-exclude>
> <parser-exclude class="org.apache.tika.parser.ocr.TesseractOCRParser"/>
> </parser>
> <parser class="org.apache.tika.parser.pdf.PDFParser">
> <mime>application/pdf</mime>
> </parser>
> </parsers>
> </properties>
> {code}
> So, the idea is - to enable the Tesseract parser for PDF format only.
> But this configuration disables the Tesseract completely.
> Is it the expected behaviour or a bug?
> Thank you!
