I just released one on github: https://github.com/QHedgeTech/cpp-elasticsearch .
There is one home http client, but it can be easily connected to libcurl. It is still minimal, I hope that you are contributing to meet your needs.
cpp-elasticsearch is a small C ++ API for elasticsearch search, it aims to become official. The documentation is yet to come, as well as the Getting Started page.
The actual version is minimal and was developed for the needs of Q-Hedge Technologies. This code uses C ++ 11 functions.
