Looking for a search function

Wordprss version 3.6
NextGen Gallery version 2.0
theme: Custom Community Pro version 1.17

I am looking for a search function that will search the description and tags attached to images in NextGen gallery. At present I have installed a google search function that will search page content and image titles, but when I choose an image it will only take me to the page that the gallery is inserted in rather than the image itself. I found this: http://alexrabe.de/2010/01/13/search-for-images/

but it is from a few years ago. Anyone know of a solution?

I am new to this forum so let me know if more information is needed.
