Tweak recognizePDF to avoid false positives: only count lines with more than 3 words (since we drop first and last later) as cleaned lines, increase number of pages read and number of lines away from median length as good lines (due to more stringent selection criteria), do not attempt to query google with a short query if we run out of lines, try to pick lines for a query that are not next to each other (to avoid finding articles that quote the article we're looking for)
