Concerning keywords in the description field of properties: i think
that is a shortcoming of the current autocomplete API that i'm using,
which is the same one Wikidata uses for the searchbox in the top-right
corner. Apparently they're not indexing those keywords, which makes it
difficult for me to also include them in my search.

Where is the documentation for this feature? I have been getting a number of interesting comments from GLAMs about the difficulty of using Authority Controls within their in-house Content management systems. I feel like this API might be a really tangible way of promoting Wikidata as facilitating consistent identifiers for metadata.

Cheers,

Alex
