+# Installing & Enabling RediSearch
+
+The E-Commerce module of ERPNext uses RediSearch to enable superfast search functionality which is highly configurable via `E-Commerce Settings`.
+
+Once installed and configured, RediSearch will be used to super charge the search functionality of the E-Commerce website. This includes features like fuzzy-word searching, autocomplete, results ranking and customizable field indexing.
+
+## Pre-requisites
+
+1. The normal Frappe Framework and ERPNext Setup
+
+2. Redis 6+
+
+## Installation Instructions
+
+```bash
+$ git clone --recursive https://github.com/RediSearch/RediSearch.git
+$ cd RediSearch
+$ sudo make setup # Remove `sudo` on macOS
+$ make build
+```
+
+On successful completion of the above instructions, a `redisearch.so` binary file will be generated in the `RediSearch/build` directory.
+
+Move this binary to the `/etc` directory and restart your Frappe Server:
+
+```bash
+sudo mv build/redisearch.so /etc/
+```
+
+Now, open the `redis_cache.conf` file located in the `config` directory (inside the bench directory). Add the following line before the `save ""` line and then restart bench server:
+
+```bash
+loadmodule /etc/redisearch.so
+```
+
+This will load the redisearch module at startup. You can check if the module was loaded successfully by running the following command in the `redis-cli`:
+
+```bash
+> MODULE LIST
+```
+
+and `search` should be one of the modules.
+
+You can also load the module on a running redis instance by running the following command in the `redis-cli`:
+
+```bash
+> MODULE LOAD /etc/redisearch.so
+```
+
+> We placed the `redisearch.so` module in the `/etc` directory, but it can be placed anywhere in the file system. We have used this directory because in the future the `loadmodule` line will be populated in the config file automatically and it will assume the binary is in the `/etc` directory.
+
+> More detailed instructions can be found [here](https://oss.redislabs.com/redisearch/Quick_Start/#building_and_running_from_source).
