Don't get me wrong, google had thousands of results. However, they were short book manuscripts, book ads, or one-paragraph writings that were not too informative. My search terms were various forms of "German economy early 1900", and late 1800.
Bing had some useless results too, but they were far (and I do mean far) more useful and relevance than google. It even linked to some very informative encyclopedias entries, and contained less results that are advertisements.
