Arch is an open source extension of apache nutch (a popular, highly scalable general purpose search engine) for intranet search. Not happy with your corporate search engine? Not surprising, very few people are. To the best of our knowledge, there are no intranet engines that work as well as the google s global web search does.

There is a fundamental reason for this: the algorithms used by google on the global web (or similar) do not work nearly as well on intranets for the lack of statistical data. Arch (finally. ) solves this problem. It uses a novel method to deliver high precision search results that works great.

Don t believe it? Blind test evaluation tools are included. You can deploy arch and compare its performance to your current search engine and/or google (on the public part of your site) using a blind test methodology.


In addition to the excellent search quality, arch has many features critical for corporate environments:

Document level security

Users can find only documents that they are authorized to see

Inexpensive index updates

Arch is able to keep indexes up to date and avoid regular complete site recrawling

24/7 availabilty

There is always a working index available, even if a crawl fails

Faceted search 'out of the box'

The source code is included

High performance and scalability
