Has anyone tried the Lightroom plug-in 'Excire' for searching/keywording? It searches your Lightroom catalogue for similar images based on image content as well as existing keywords.

Reason I ask - I don't use Lightroom but I use IMatch for keywording and the developer of IMatch is thinking of developing a plug-in for IMatch.
Some users on the IMatch forum seem to rate it highly - https://www.photools.com/community/index.php?topic=6708.0
