SpringSearch turns your Obsidian vault into a fully searchable knowledge base, powered by Spring Boot and MongoDB Atlas Search.
It supports full-text queries, autocomplete, fuzzy matching, and custom boosting for prioritizing your most relevant notes — all exposed via a simple REST API.

• Full-text search: Query across title, tags, and content fields.
• Autocomplete: Type-ahead search for instant suggestions.
• Fuzzy matching: Tolerates typos and misspellings in queries.
• Custom boosting: Prioritize matches in specific fields like title or tags.
• Obsidian integration: Automatically parses Markdown files (with frontmatter) into MongoDB documents.
• REST API: Simple endpoints for searching notes.

• Java 24+ (or update pom.xml to your installed version)
• Maven 3.9+
• MongoDB Atlas (free M0 cluster is sufficient)
• An existing Obsidian Vault containing Markdown notes with optional frontmatter.

git clone https://github.com/mongodb-developer/SpringSearch.git
cd SpringSearch

Edit the src/main/resources/application.properties file:

spring.data.mongodb.uri=${MONGODB_URI}
spring.data.mongodb.database=obsidian
notes.folder.path=/path/to/your/vault

Make sure your MongoDB Atlas cluster has a Search Index with this configuration:

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "title": [
        { "type": "string" },
        { "type": "autocomplete" }
      ],
      "tags": { "type": "string" },
      "content": { "type": "string" }
    }
  }
}

MONGODB_URI="your-mongodb-uri" mvn spring-boot:run

Basic search:

GET /api/notes/search?q=<query>

Boosted by title:

GET /api/notes/search/boost-title?q=<query>

Autocomplete + fuzzy matching:

GET /api/notes/search/autocomplete-fuzzy?q=<query>

All-in-one (boosting + autocomplete + fuzzy):

GET /api/notes/search/autocomplete-fuzzy-boosted?q=<query>
