In photo search, you can search photos using keywords. Keywords associated with photos are labels automatically extracted by artificial intelligence.
Search with multiple keywords is not possible. Please specify only one keyword.
In order to search photos, you need to add the url property to the photo's URL.
The value of the url property is the URL of the page on which the photo is posted.

If you use the paid photo search API, you can place a photo search function on your own site.
