I did a search on factset on https://www.quantopian.com/docs/index and got interesting results. There is a preponderance of estimates data sets returned and we just had a mini contest requiring the use of estimates data. So, I'm wondering how the documentation search works? Are the research results weighted in some way? It would seem to be more than coincidental given the number of FactSet data sets that a search on factset would, just by chance, return so many estimates data set results. My hypothesis is that there were lots of searches for estimates data recently, and thus the documentation search engine weighted estimates data sets more highly than others in a factset search.
