Setting up MeiliSearch for LibreChat

See: Search feature in LibreChat for a quick overview.

MeiliSearch is a powerful, open-source search engine that enhances LibreChat’s functionality by enabling full-text search, typo tolerance, and instant search results for past conversations.

Follow these steps to set up MeiliSearch for LibreChat:

1. Download MeiliSearch

Go to the MeiliSearch GitHub releases page: https://github.com/meilisearch/meilisearch/releases
Download the latest version of MeiliSearch for your operating system (e.g., meilisearch-linux-amd64.tar.gz for Linux, meilisearch-macos-amd64 for macOS, or meilisearch-windows-amd64.zip for Windows).

2. Extract/Install MeiliSearch

Linux/macOS: Extract the downloaded archive to a directory of your choice.
Windows: Extract the ZIP file to a directory of your choice.

3. Make the MeiliSearch Binary Executable (Linux/macOS)

Open a terminal and navigate to the directory where you extracted MeiliSearch.
Run the following command to make the binary executable:
Make the MeiliSearch Binary Executable
```
chmod +x meilisearch
```

4. Generate a Master Key

Open a terminal (or Command Prompt on Windows) and navigate to the MeiliSearch directory.
Run the following command to generate a Master Key:
Generate a Master Key
```
./meilisearch --generate-master-key
```
Copy the generated Master Key as you’ll need it later.

5. Start MeiliSearch

In the same terminal, run the following command to start MeiliSearch, replacing <your_master_key> with the Master Key you generated in the previous step:
Start MeiliSearch
```
./meilisearch --master-key=<your_master_key>
```
MeiliSearch will now start running on the default port (7700).

6. Update LibreChat’s Environment Variables

Open the .env file in the root directory of your LibreChat project.

Add or update the following lines with your MeiliSearch configuration:

.env

SEARCH=true
MEILI_NO_ANALYTICS=true
MEILI_HOST=http://localhost:7700
MEILI_MASTER_KEY=<your_master_key>

Replace <your_master_key> with the Master Key you generated earlier.

7. Start/Restart LibreChat

Start or restart your LibreChat application.

That’s it! With MeiliSearch set up and configured, LibreChat should now have the Conversation search feature enabled, allowing users to perform full-text searches, benefit from typo tolerance, and experience instant search results for their past conversations.

Note: Make sure to keep the MeiliSearch process running in the background for the search functionality to work correctly. You may want to set up a script or service to keep MeiliSearch running persistently.
