Search function for publicly shared boards

I like the possibility to share boards publicly.
We’d love to integrate their iframes into our members’ portal to offer access to all relevant partner details within our network.

The ONLY reason we are still not able to do so is the missing search functionality (search for text, tags, labels and so on). Of course you can do a classy browser search via “cmd+f” but this only shows search results within the displayed rows and columns. Data you’d need to scroll for is NOT INCLUDED.

Would be so great to add this feature to publicly shared boards.

Thanks so much
