CipherCloud's website now clearly states, here, that CipherCloud DOES NOT use homomorphic encryption.
This also states that CipherCloud DOES NOT implement 1:1 mapping or ECB mode in any customer deployment. Other statements are next to acknowledging that CipherCloud's early demos did that, citing the will to illustrate the functionality, features that where ...

Here's what's common in both scenarios: Alice holds $x$ and wants to compute $f(x)$. A server Bob will help with the computation. Alice doesn't want Bob to learn $x$, so she sends some encoding of $x$ that hides $x$. Bob does some work and sends back a result from which Alice can infer $f(x)$.
The two settings differ on: (1) how Bob is allowed to help Alice ...

That paper refers to the numerical ordering, while what would be relevant for searchable encryption without changes to the providers is the substring ordering. $\:$ (Thus, their bound does not apply.)
What do you mean by "existing queries in a database"?
If your assumption holds, then
{
Encryption must be deterministic (given the key), since different ...
