First of all, a more manageable solution is currently on develop, but for the moment, a quick workaround would be to change manually the following .dat files you’ll find in the plugin-name/def folder:
-Add the following line at the end of searchengines.dat:
Bing|www.bing.com/search|q|
This would allow to show the search engine when a user come to your site from Bing.
-Add the following line at the end of spider.dat
Bing Bot|bingbot|https://www.bing.com/bingbot.htm|
This line would allow to show bing bot when the agent is indexing your site.
We’re currently analyzing the best way to keep this files updated.
