"Additional Info" Field Search Results?

[LinesideSouthEast 0]

According to the Alamy Image Manager the "Additional Info/Tell Us More About Your Image" field should not be searchable. However going through my recent Alamy measures results I have found multiple image showing up in search results for keywords that only appear in the "Additional Info" field. Anyone else finding this happening?

Are you sure the keyword concerned doesn't appear in the caption, which is searchable? Can you give an example of an image of yours and keyword which is being found only in the additional info field?
