What i would do is put this in the Google search bar like this "why you want the subject...i.e remove or change ect in these quotes"

They will direct you to the thing that you really are looking for and that will save you the search in a lot of trends.

When you have done that and you want to see and look into the service that you are looking for check with the Google trends as well on that subject and when you have found out and want to use that service then check for the history on that site under safe search as well.

Good luck and i hope i have helped you out.
