Summa in a Nutshell
Summa is a fast modular and scalable search engine written in Java. Summa is characterized by:
Integrated search. Summa can simultaneously access a number of different data and data sources and expose it in a unified interface.
Modular design. The Summa search system consists of a set of independent modules, which makes it simple and easy to maintain and upgrade.
Scalable. Summa supports a distributed architecture and can be scaled up or down to handle any amount of data.
Open standards. Summa is based upon modern web technologies and standards, and don’t include any proprietary codes or elements.
Failure tolerant. If a single source of data or service should fail, Summa will continue without that specific source.
