# RediSearch Administration Guide
RediSearch doesn't require any configuration to work, but there are a few things worth noting when running RediSearch on top of Redis.
## Persistence
RediSearch supports both RDB and AOF based persistence. For a pure RDB set-up, nothing special is needed beyond the standard Redis RDB configuration.
### AOF Persistence
While RediSearch supports working with AOF based persistence, as of version 1.1.0 it **does not support** "classic AOF" mode, which uses AOF rewriting. Instead, it only supports AOF with RDB preamble mode. In this mode, rewriting the AOF log just creates an RDB file, which is appended to.
To enable AOF persistence with RediSearch, add the two following lines to your redis.conf:
```
appendonly yes
aof-use-rdb-preamble yes
```
## Master/Slave Replication
RediSearch supports replication inherently, and using a master/slave set-up, you can use slaves for high availability. On top of that, slaves can be used for searching, to load-balance read traffic.
## Cluster Support
RediSearch will not work correctly on a cluster.
