Quick Start Guide for RediSearch:

Building and running:

git clone https://github.com/RedisLabsModules/RediSearch.git
cd RediSearch/src
make all

# Assuming you have a redis build from the unstable branch:
/path/to/redis-server --loadmodule ./redisearch.so

Creating an index with fields and weights (default weight is 1.0):

127.0.0.1:6379> FT.CREATE myIdx SCHEMA title TEXT WEIGHT 5.0 body TEXT url TEXT
OK 

Adding documents to the index:

127.0.0.1:6379> FT.ADD myIdx doc1 1.0 FIELDS title "hello world" body "lorem ipsum" url "http://redis.io" 
OK

Searching the index:

127.0.0.1:6379> FT.SEARCH myIdx "hello world" LIMIT 0 10
1) (integer) 1
2) "doc1"
3) 1) "title"
   2) "hello world"
   3) "body"
   4) "lorem ipsum"
   5) "url"
   6) "http://redis.io"

NOTE: Input is expected to be valid utf-8 or ascii. The engine cannot handle wide character unicode at the moment.

Dropping the index:

127.0.0.1:6379> FT.DROP myIdx
OK

Adding and getting Auto-complete suggestions:

127.0.0.1:6379> FT.SUGADD autocomplete "hello world" 100
OK

127.0.0.1:6379> FT.SUGGET autocomplete "he"
1) "hello world"
