I should say it's 30 "units"/day not 10k requests. Depending on the number of results you get back. For all on-peak requests that would be a maximum of 10k search requests. Off-peak it would be 30k search requests. If you needed more results per request then the amount of free requests would be less. Spelling requests would also be counted as the same rate as off-peak. You can mix and match as much as you want.
