I am not talking about regional search engines.
Nor specialists like Deep Dyve.
After so much takeover/mergers, we have?
Google
Microsoft/Yahoo
Ask
Gigablast (more like a database of spamdexers)
Now I tried lygo.com and found something that did not come up in
those above. So do they still run their own crawler?
