How should one formulate a search query for kgsearch.googleapis.com to find all entries in a given category? For example, if I wanted to search for things in the Schema.org category applicationCategory, how would I do it? Something like the following,
https://kgsearch.googleapis.com/v1/entities:search?query=c&types=applicationCategory&key=MYKEYHERE
results in an error ("Request contains an invalid argument"). Something like the following,
https://kgsearch.googleapis.com/v1/entities:search?query=c&types=Thing&key=MYKEYHERE
is not specific enough, and returns unrelated results.
