PAGE_CHAR_STARTS	A list of character offsets that denote where in the rich_doc_text each page starts
PAGE_DOCS	A list of RichDoc objects where each item corresponds to the RichDoc of a single page, in order
PDF_URL_COL	The URL/file location of the PDF
PKL_COL	Serialized version of the RichDoc object
SPAN_END_CHAR_OFFSET	The offset from the char_end of the last word in a span
SPAN_END_WORD_ID	The id of the word at the end of the span, relative to all other words in the document
SPAN_NGRAM	An n-gram of the words in the span; See Ngram for more
SPAN_PAGE_ID	The page # that the span belongs to
