Sharing metadata

I have created a Lightroom CC album.  Each photo's metadata includes keywords in the tagging section and locations in the information section.  A few questions have emerged.

When I share the album, viewers can click the info button on the right to see the location and other details (image history, etc.).  But how can they see the keywords?  These are essential, since they contain a lot information about the content of the images.

Moving beyond basic sharing, is there any way to set up a shared Lightroom album so that the metadata is searchable?  I've read several postings indicating that this is not possible.  Is that really true?  If so, are there any other options?  I'd rather not have to pay for a license on another platform like SmugMug.

Thanks for your help.
