Lucid Imagination has made it easy to search the Lucene world with a very cool multi-select, faceted, interface.

Its just as easy to add that search engine to Firefox’s search box:

1. Navigate to lucidimagination.com/search

2. Locate Firefox’s built-in search component on the toolbar (or add it to the toolbar)

3. Click the down arrow (where you change the search engine), and click “Add LucidFind”

4. Search the whole Lucene ecosystem in one shot
