[Plugin: NextGEN Gallery] search bar to work with NextGEN gallery tags

can anyone help me with having the ability to search my nextGEN gallery tags? i’ve noticed on the NextGEN gallery page it works (except i’d like my search results to return singlepic).
When i search ‘irlan’ on the nextGEN gallery site it returns this:
https://nextgen-gallery.com/?s=irland

i’ve tried tagclouds in text widgets and the basic search bar but nothing seems to search through my nextGEN gallery tags.

please help, i’m no developer either which makes things much worse!
