🔍 Setting Up Semantic Search with LM Studio
Hydrate supports semantic search using local embeddings via LM Studio. This lets you search your vault by meaning, not just keywords.
Setup Steps
- Install LM Studio from lmstudio.ai
- Download an embedding model - search for
nomic-embed-textin LM Studio and download it - Start the local server in LM Studio (Developer tab → Start Server)
- Configure Hydrate:
- Open Hydrate settings in Obsidian
- Enable "Remote Embeddings"
- Set the embedding URL to:
http://localhost:1234/v1/embeddings - Set the model name to match your downloaded model (e.g.,
nomic-embed-text)
- Index your vault - use the "Reindex Vault" button in settings
Once indexed, Hydrate will suggest relevant notes during chat and you can search by meaning across your entire vault.
