Dear colleagues,
to keep in touch with the „dramatic growth of Open Access“ we are happy to
announce a new test version of the OAI-Search-Engine BASE (Bielefeld Academic
Search Engine, www.base-search.net) in our BASE Lab. The new version is
developed on Lucene/Solr instead of FAST/Microsoft and has a VuFind-Search-
Interface, which you can try here directly:
http://baselab.ub.uni-bielefeld.de/?l=en
The FAST index was pushed to a limit last year, but because the harvesting of
repositories continued, the test index in our BASE Lab contains about one
million documents more. Some repositories are not included in BASE Lab for
technical reasons.
New repositories will be included in our new system only, please understand
that we need some time for that; index update happens not on a weekly basis
yet. There is also new BASE-OAI-PMH blog for those, who want to particapte
from our experience in metadata harvesting:

Unsurprisingly the FAST software works a little different from Lucene/Solr. At
this stage, there is no multilingual search (using Eurovoc Thesaurus) and no
lemmatization for different languages in Lucene. We have included the Porter
Stemmer, but if someone gives us the money for example the „Rosette
Linguistsics Platform“, we would be much happier ;-)). Of course there are
some new features, like sending results to an email-adress or RSS-Feeds.
In the next few months we want to finish the migration but for now we are
looking forward for some feedback .
About BASE:
BASE is the name of the multi-disciplinary search engine for scientifically
relevant OAI-Sources which was created and developed by Bielefeld University
