3D FlipBook - Add a global search to flipbook archive?

Dear Iberezansky,

we have bought the plugin license for a publisher, with a big number of magazines.

Within each flipbook there is a nice local search opportunity for users.

But what is the best option to add a global search, across all magazines/flipbooks? Is there a code option you can suggest or should we look into adding a third party search engine??

Looking forward to your advice

Kind regards Henrik
