Bobo-Browse

is a Faceted Search implementation written purely in Java, an extension of Apache Lucene.

While Lucene is good with unstructured data, Bobo fills in the missing piece to handle semi-structured and structured data.

Bobo Browse is an information retrieval technology that provides navigational browsing into a semi-structured dataset. Beyond the result set from queries and selections, Bobo Browse also provides the facets from this point of browsing.

Logical Architecture

Some of the extra features:

No need for cache warm-up for the system to perform.
multi value sort - sort documents on fields that have multiple values per doc, .e.g tokenized fields
fast field value retrieval - over 30x faster than IndexReader.document(int docid)
facet count distribution analysis
stable and small memory footprint
support for runtime faceting
result merge library for distributed facet search
...

Release: - Bobo Browse 2.5.0-rc1 is released! (2/15/2010)
