It's not nearly that simple. If your encryption scheme is deterministic then this leaks a ton of information, because anybody with the public key can just encrypt lots of values to reconstruct a mapping between plaintexts and ciphertexts. On the other hand, if your encryption scheme isn't deterministic, then you can't predict what encrypted value you should query for.

Those kinds of problems have never stopped any company from offering a service with a lot of nice graphics on the home page.

Add random data to it, so that all (equivalent) data is the same length. For example, if you have a four byte field that represents some monetary value, add four more bytes of random data and encrypt it.

How would you run queries over that?
