I would like better search functionality on Hive. Looking at the repository https://github.com/esteemapp/hive2elastic, I don't see any mention of a license.

An open source license is a prerequisite for me to support this work. Personally, I think the BSD-2-Clause Plus Patent License would be the best choice for your Python codebase, but any common permissive open source license would probably be sufficient.

Without a license, the community is not able to reuse and build off your code.
