The parsed text of a file's pages, for reading and citing. Give page_numbers to read those pages in order, or query to find the pages most relevant to it (best first, up to limit), or both to search within those pages. Read a document page by page rather than all at once; for PDFs total_pages on the file says how many there are (other formats report -1 but are readable the same way). A requested page that is missing from the result has too little text to have been indexed (a chart, a scan). Cite a page by its page_number, for example as knowledge record evidence. Only files whose status is INDEXED_SUCCESSFULLY have pages.
