A search security model should be implemented. At the moment every
user can search every document. However, in the future, the intent is
to implement a search strategy that restricts the results returned
depending on whether the user is allowed to access the documents,
This will be required especially if the system is to be used to index
internal documents, which may, for instance, include HR or restricted
project documents.
In addition, the following enhancements to the existing systems are being
considered.
■
Allowing users to provide feedback/annotations on individual
documents. This would require the SOLR Index to be integrated with
a database to hold the annotations, so that subsequent updates to the
documents from the original source did not result in the loss of the
annotations.
■
The standardising of the pipeline, utilising other tools such as Nutch
[12] (to crawl fi le and web infrastructures) and Tika (to extract text
and meta-data from a wide range of document types), to extend the
reach of the documents indexed.
In addition, more uses of a single, enhanced data source are being
discovered on an almost daily basis, meaning that new simple business
applications are being developed by various informaticians and developers
within AZ.

Overall, our experience of open source technologies as applied to solve
business problems has been extremely positive. Even after recent
comparisons to commercial software, SOLR still appears highly
competitive and truly optimised for faceted search. Prefuse continues to
grow and, with the advent of Flare, has made steps to wider adoption
with improved visualisation performance.
If we were to do this again, we would invest in both SOLR and Prefuse/
Flare, with a capability to be able to build business applications over the
scientifi c content. Looking back, it appears that we have several different
technologies in the mix and in hindsight, much of what we have developed
could probably be designed through using just open source approaches.
One area that we would change would be to have a closer connection
to the open source community. Currently the relationship is very
