Thank you for providing a Steem search other than Google!
Yacy might make your indexing efforts more distributed and cost effective.
Yacy is a great Distributed Search engine. You can host a node that only indexes Steem in collaboration with anyone else who wants to index steem and share results. Yacy runs on Desktops, laptops and servers. Linux, Windows and Mac.
There is also a built in interface for your site that works out of the box. Together we are strong. Take a look if you're interested.
I have a basic demo that indexed some of steem and reddit on my Desktop here. http://camb.hopto.org:8090/
(this demo won't be up much longer)
I will be moving it to a proper server soon and begin indexing only distributed networks.
Good luck!
Very interesting, I'll be looking into this. :)
Yacy has been an undervalued project for years. It works great. If you have any questions getting started, feel free to ask me and I will answer as best as I can.
