Lucene Search Engine
Lucene is a Java-based open source toolkit for text indexing and
searching.
OAI Protocol
Interoperability standard that provides a convenient way to share
metadata among library repositories. The OAI standard was developed
to provide a simple method to support the streaming of metadata from
one repository to another, and ultimately to a provider of user services
such as searching, browsing or annotation.
Future Enhancements
Our project can be enhanced to implement more advanced
search capabilities like category search and site search. If
the indexer and the searcher is implemented similar to the
other high performance search engine construction, our
search engine performance can be extended to the very
great extent
Conclusion
On implementing this project, we learnt the technology
Java – servlet and the database Microsoft Access and SQL.
We also learnt the details about the network performance
issues and OAI protocol. We grasped the concepts of
indexing and searching and how they are implemented in
any search engine to provide the better performance
