If you are doing large-scale processing of untrusted documents, I'd highly
recommend the config.xml option with tika-server. Keep your file
processing out of your process. :D
You do need the entry for default parser. Given the parser sort order, you
shouldn't need to exclude, but I do it as good practice.
I'd like to figure out a way to set the field params in the default
parsers, e.g. don't touch all the other parsers, but make the following
updates to the PDFParser that was already loaded as part of the usual
service loading process.
<*parser class="org.apache.tika.parser.DefaultParser"*>
<*parser class="org.apache.tika.parser.pdf.PDFParser"*>
<*params*>
<*param name="extractInlineImages" type="bool"*>false</
*param*>
<*param name="ocrStrategy" type="string"*>
OCR_AND_TEXT_EXTRACTION</*param*>
</*params*>
</*parser*>
</*parser*>
