1) Plus, those files are binaries sometimes with metadata, specific crawlers need to understand them. html is a plain text
2) Yes, different data schemes. Sometimes I replicate the same core and make some A-B tests with different weights, filters etc etc and some people like to creare CoreA and CoreB with the same schema and hammer CoreA with updates and commits and optmizes, they make it available for searches while hammering CoreB. Then swap again. This produces faster searches. alexei martchenko Facebook <http://www.facebook.com/alexeiramone> | Linkedin<http://br.linkedin.com/in/alexeimartchenko>| Steam <http://steamcommunity.com/id/alexeiramone/> | 4sq<https://pt.foursquare.com/alexeiramone>| Skype: alexeiramone | Github <https://github.com/alexeiramone> | (11) 9 7613.0966 | 2014-01-28 Jack Krupansky <j...@basetechnology.com> > 1.
