This patch is in preview mode and can be useful for the discussion. It's not functional yet, but this will be changed in the future.

The upcoming changes would allow handling short queries introduced in https://reviews.llvm.org/D50337 in a more efficient manner.

@ioeric proposed to generate unigrams for the first letter of the identifier so that the index would only perform prefix match for one-letter completion requests, which I think would be a great performance improvement.
