Holumbus is a Haskell library which provides the basic building blocks for creating powerful indexing and search applications. This includes a framework for distributed crawling and indexing as well as distributed query processing. Additionally, a full-fledged distributed Map-Reduce framework is included.

To explore the power of Holumbus, have a look at Hayoo!, a Haskell API search engine, or download (see below) Holumbus and check out some of the included examples.

The Holumbus framework ist split into four sub-packages, which build upon each other but may also be used independently:

The Holumbus Distribution Library

The Holumbus Storage System

The Holumbus MapReduce Framework

The Holumbus Search Engine

A cookbook for the MapReduce Framework
