sist2

sist2 (Simple incremental search tool) is a lightning-fast file system indexer that scans directories and builds a searchable index of file contents and metadata. It provides a mobile-friendly web interface and supports either Elasticsearch or a lightweight SQLite (FTS5) search backend.

Key Features

• Incremental, multi-threaded scanning optimized for speed and low memory usage
• Web UI for searching and browsing results, including thumbnails and metadata
• Supports Elasticsearch indexing or a simpler SQLite-based search backend
• Content extraction and metadata parsing for many common formats (documents, media, ebooks)
• Recursive scanning inside archive files (including archives within archives)
• Optional OCR via Tesseract for images and supported ebook/document formats
• Manual tagging in the UI and automatic tagging via user scripts
• Basic statistics and disk utilization visualizations

Use Cases

• Personal or team “desktop search” for large document and media collections
• Building a searchable archive of mixed file types (PDFs, photos, videos, ebooks)
• Indexing NAS or server directories to quickly locate files by content or metadata

Limitations and Considerations

• Elasticsearch provides more features but has a significantly higher resource footprint than SQLite
• Archive scanning is single-threaded and some seek-heavy media formats in archives may be limited

sist2 is well-suited for users who want fast local file indexing with a modern web search experience and flexible backend options depending on resources and feature needs.
