Luke - Lucene Index Toolbox

Lucene is an Open Source, mature and high-performance Java search engine. It is highly flexible, and scalable from hundreds to millions of documents.

Luke is a handy development and diagnostic tool, which accesses already existing Lucene indexes and allows you to display and modify their content in several ways:

• browse by document number, or by term
• view documents / copy to clipboard
• retrieve a ranked list of most frequent terms
• execute a search, and browse the results
• analyze search results
• selectively delete documents from the index
• reconstruct the original document fields, edit them and re-insert to the index
• optimize indexes
• and much more...
