Open Source alternative to "Google Appliance" for intranet search? [closed]

Are there any alternative open source solutions (with a web console)?

Solution 1:

Try this: http://www.flax.co.uk/

(I have no experience with this product or other enterprise search products).

Solution 2:

Solr, from the Apache Lucene project. Excerpt from the web site

http://lucene.apache.org/solr/

Solr is an open source enterprise search server based on the Lucene Java search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, a web administration interface and many more features. It runs in a Java servlet container such as Tomcat.

Solution 3:

I have used 'htdig' in past for intranet search. It is good and indexes pdf documents by default. Once you can add filters that can translate documents to text format for indexing, it will start supporting other formats as well.
