# ZincSearch — Lightweight Elasticsearch Alternative in Go

> ZincSearch is a search engine written in Go that provides full-text indexing and search with a fraction of the resource requirements of Elasticsearch. It offers an Elasticsearch-compatible API, a built-in web UI, and runs as a single binary.

## Install

Save as a script file and run:

# ZincSearch — Lightweight Elasticsearch Alternative in Go

## Quick Use
```bash
# Download and run
mkdir -p data
ZINC_FIRST_ADMIN_USER=admin ZINC_FIRST_ADMIN_PASSWORD=changeme 
  ZINC_DATA_PATH=./data ./zincsearch

# Or run with Docker
docker run -p 4080:4080 -e ZINC_FIRST_ADMIN_USER=admin 
  -e ZINC_FIRST_ADMIN_PASSWORD=changeme public.ecr.aws/zinclabs/zincsearch:latest

# Index a document via API
curl -u admin:changeme -X POST http://localhost:4080/api/myindex/_doc 
  -d '{"name":"hello","message":"world"}'
```

## Introduction
ZincSearch aims to be a drop-in alternative to Elasticsearch for use cases where you need full-text search without the operational overhead of running a JVM-based cluster. It stores data using bluge, a pure Go indexing library, and exposes an Elasticsearch-compatible query API so existing integrations often work without changes.

## What ZincSearch Does
- Indexes JSON documents and provides full-text search with relevance scoring
- Supports an Elasticsearch-compatible bulk ingest and search API
- Includes a built-in web UI for querying, index management, and log exploration
- Stores data on local disk with support for S3-compatible object storage backends
- Handles log aggregation workflows with built-in timestamp-aware index patterns

## Architecture Overview
ZincSearch runs as a single Go binary with an embedded bluge index engine. Documents are indexed into shards stored on disk or in S3. The query layer parses Elasticsearch-style JSON queries and translates them into bluge search requests. The built-in web UI is served from embedded static assets. There is no separate coordination layer or cluster manager, keeping the operational footprint minimal.

## Self-Hosting & Configuration
- Single binary with no JVM or external dependencies; starts in seconds
- Configure via environment variables for admin credentials, data path, and storage backend
- Supports local disk or S3-compatible storage for index data
- Set retention policies and index rollover for time-series log data
- Deploy behind a reverse proxy for TLS; supports basic auth and token-based API keys

## Key Features
- Elasticsearch-compatible ingest and search API for easy migration
- Sub-second startup time and low memory footprint compared to Elasticsearch
- Built-in web UI with query editor, index browser, and real-time log viewer
- Schema-less indexing with automatic field type detection
- Supports aggregations, highlighting, and multi-index search queries

## Comparison with Similar Tools
- **Elasticsearch** — Full-featured distributed search; much higher resource usage and operational complexity
- **Meilisearch** — Focused on instant typo-tolerant search for user-facing apps; different query model
- **Typesense** — Fast search with tuning simplicity; stronger ranking controls but no log aggregation focus
- **ManticoreSearch** — SQL-based search engine; stronger for structured queries and real-time indexes
- **OpenSearch** — AWS fork of Elasticsearch; same architecture and resource profile

## FAQ
**Q: Can ZincSearch replace Elasticsearch in production?**
A: For small-to-medium workloads and log aggregation it works well. Very large clusters with complex aggregations may still need Elasticsearch.

**Q: Does it support distributed clusters?**
A: ZincSearch is primarily a single-node engine. For high availability, use S3 storage with multiple read replicas.

**Q: Is the Elasticsearch API fully compatible?**
A: It covers the most common APIs including bulk, search, and mappings. Some advanced features like scroll or ML are not supported.

**Q: What log collectors work with ZincSearch?**
A: Fluent Bit, Fluentd, Vector, and any tool that sends data to the Elasticsearch bulk API.
