Best search engine for research organisation's website

Question

We are a government funded research organisation providing HPC facilities. The website has a lot of information and we would like to make it available through a search engine.

Can you recommend an open source, preferably Java or Python based project, that provides fast and deep search results.

Thanks

Answer 1

Lucene is probably a good match. It is open source, supports Java, has a lot of features and is easy to extend/ingrate.

Answer 2

What do you want to search for? On the site http://java-source.net/open-source/search-engines you get a good overview over different solutions.
