Description

Actually there is no possibility to hand over some additional configuration by document extracting with ExtractingRequestHandler/ExtractingDocumentLoader.

For example I need to put org.apache.tika.parser.pdf.PDFParserConfig with "extractInlineImages" set to true in ParseContext to trigger extraction/OCR recognizing of embedded images from pdf.

It would be nice to have possibility to configure created ParseContext due xml-config file like TikaConfig does.

I would suggest to have following:

solrconfig.xml:
<requestHandler name="/update/extract" class="org.apache.solr.handler.extraction.ExtractingRequestHandler">
<str name="parseContext.config">parseContext.config</str>
</requestHandler>

parseContext.config:

<entries>
<entry class="org.apache.tika.parser.pdf.PDFParserConfig" value="org.apache.tika.parser.pdf.PDFParserConfig">
<property name="extractInlineImages" value="true"/>
</entry>
</entries>
