textproc/redisearch2: New port
RediSearch is a source available Full-Text and Secondary Index engine
over Redis, developed by Redis Labs.
Redisearch implements a search engine on top of Redis, but unlike other
Redis search libraries, it does not use internal data structures like
sorted sets.
This also enables more advanced features, like exact phrase matching and
numeric filtering for text queries, that are not possible or efficient
with traditional Redis search approaches.
This is the 2.10.X branch of redisearch. This is also the last version
from 2.X branch. This is why it's suffixed with 2 instead of 210.
