Before having a look at the implementation, is there any reason the two
search types are called "rpc" and "web" (other than "rpc" is how the RPC
interface used to behave and "web" is how the RPC interface used to
behave)? If not, I think we should choose a different naming that is
more intuitive and self-explanatory.

Going a step further, would it be much more work to instead make the
interface more powerful, use conjunctive search by default and perform
exact matches for phrases put in quotes, such as

    "arch linux" package

matching everything that contains the strings "arch linux" and
"package"? With that, we wouldn't even have to distinguish different
search types (but we may need to bump the API version).

Best regards,
Lukas
