So I have two questions that I am unable to locate answers too in the help area. 

1) In a report, the search drop-down shows fields I do not want people to be able to search by. How do I change what fields can and can not be searched by in the report? for example, I have some image fields and I do not want people to be able to search by those fields in the report.

2) Along those same lines there is the more options function in my report that i would like to get rid of completly, unfortunity the only way i have found to do that is to turn off the menu but that get rid of my search functionality as well.
