A new scholarly search engine

Using Google custom search to outsmart Google Scholar, that is a smart idea from the people behind openDOAR (Directory of Open Access Repositories). Try it at yourself. You get really accessible results, not those that require a 50$ fee to get hold of the results which is often the case with Google Scholar. It has also an advantage over OAISTER, that fulltext searching is possible whereas OAISTER only allow bibliographic searching.
Of course it is not yet te ideal solution, we know that the Google bot is very slow at harvesting information from our repository, but a few tests did not dissappoint me on the quality of results. It certainly deserves a lot of attention, and time to test is more comprehesively. Perhaps an idea for Peter for his next pick or pan?
But it is simply a brilliant idea of using Google custom search to make a the best of the academic repositories ftxt searchable at once.
I just like it.

The concept is very nice, but the search results raise serious doubts. Searching for the word analysis gives 117 results. One should expect tens of thousands. Google seems the give just a few results to these Co-op custom search engines. Doing a search for the word analysis in the regular Google search engine limited to just one repository domain (eprints.ecs.soton.ac.uk) gives 2540 results. OpenDOAR using Google Co-op comes up with a maximum of 100-170 results, whatever your search terms are. It is seems advisable to be very specific when searching through OpenDOAR.
