BOSS Image Only - Queries count

Hello,

I have a question on how the BOSS engine counts queries.

The "BOSS Image Only" service provides 1000 queries at $0.30.

The guidelines say the results are refreshed every 3 days. This is true because If I search for the word "dog" I always retrieve the same 35 images.

Do the queries that contain the same search criteria (in this case "dog") count toward the 1000 queries/$0.30 or the count increases only when the results are refreshed?

Does anybody have any idea?

Thank you very much

Gianluca
