We have a situation here in New Zealand where each University has a repository (mainly dspace) and the National Library maintains an OAI-powered search engine that runs across them.
OAI doesn't include the full text, so searching is significantly limited. If you search for a relatively rare surname in both, you'd expect to find more in the cross-site search, but this isn't the case, because most personal names occur in the acknowledgements and bibliography, which don't make it into the OAI metadata. Compare http://researcharchive.vuw.ac.nz/search?query=yeates&submit=Go http://nzresearch.org.nz/index.php/search/results?query=yeates&x=0&y=0 The second URL is the poorer search over the larger body of documents. The nzresearch.org.nz has huge benefits, but exhaustive searching isn't really one of them. cheers stuart Walker, David wrote: > We have that use case here, John -- we are implementing separate DSpace > instances for our 23 campuses, but we also need a separate interface that can > search them all. > > We're just going to harvest the data using OAI-PMH.
