How to format .DOC documents for Watson retrieve and rank web interface uploader -

i wonder best way format .doc documents retrieve , rank web interface document uploader handles answer splitting best. (i using https://watson-retrieve-and-rank.ng.bluemix.net )

we have create set of documents , can't find guide on how reformat them (for example, if text size, bold, ... title, body of answer, etc.) improve automated answer splitting. team creating documents not able prepare them in proper json format , of doc files parsed service 1 page answer without splitting

of course, maybe there tool missing task.

thanks experience or links.

the detailed documentation @ https://www.ibm.com/watson/developercloud/doc/document-conversion/customizing.shtml#htmlau tooling using default settings document conversion service.

however, summarise, tooling split word documents @ paragraphs style used name "heading n" "n" number.

so includes existing default built-in styles in ms word (i.e. "heading 1", "heading 2", "heading 3", "heading 4", "heading 5", "heading 6", "heading 7", "heading 8", "heading 9"). includes styles create names (e.g. "heading 123")
