Wish list of search over encrypted data

The encrypted data is hosted in an untrusted server (honest-but-curious case only) and a user wants to make a "special" query and obtain only the matching data objects. I use the word "special" since you need to have some kind of an encoded query in order for the server to execute it over encrypted data without decrypting the data.

My wish list: The server should not be able to
- learn what the "special" query is
- create the "special" query by itself
- distinguish between encrypted data objects
- learn the result of the "special" query
