Hey guys! I recently configured Google CSE and thought I'd leave some tips on how to use it and what are the benefits of using it.
I personally think that Google CSE is better than IPB's default search engine but if you don't like it, you can always switch back to IPB's default by clicking the Google text and selecting 'Forums' from the dropdown menu.
Google CSE also lets the user search on Google without even leaving the forum so if you are looking for an image to add to your new topic, you can do so by searching the App Name and clicking the Images tab to display images based on your search.
Don't misuse it or the image tab will be removed! Also get images from safe sites like itunes.apple.com or appshopper or play.google.com etc.
So yeah, hope this new feature will be helpful to members and if you don't get any results using this, be sure to try out IPB's default search also.
Good luck!
Note: The Google CSE popup doesn't work very well on small screens (iPhones) which are viewing the Desktop Version of the site. Works fine on iPads though.
