Detect Lucene

Establishes

One or more public signals on the scanned page matched a known Lucene signature (catalog rules) at the time of the scan.

A sitewide install of Lucene, an active vendor contract, exclusive use, or that Lucene is still in place today.

1. 1. Enter the website URL in the scan form — homepage, pricing, checkout, or login pages usually expose the strongest Lucene signals.
2. 2. PluginView reads only public responses and scores them against the Lucene signature set (0 rules).
3. 3. Review the confidence score and text explanation for Lucene on the results page.

A confirmed Lucene match also implies these technologies are present.
