## What it is
sist2 is a fast, multi-threaded file system indexer that extracts text, metadata, and thumbnails from common file types, with OCR support via tesseract and recursive scanning inside archives. It indexes into Elasticsearch or a zero-install SQLite backend and ships a mobile-friendly web interface for searching, tagging, and visualizing disk usage.

## Use cases
- search across all files on my disk from a web interface
- build a full-text index of a directory of documents
- self-hosted file search engine for a NAS or server
- make scanned PDFs searchable with OCR
- find text inside documents buried in zip archives
- browse file metadata, tags, and disk usage visually
- incrementally re-index a large changing file tree

## When to choose
- you want fast, low-memory indexing of large file trees with incremental rescans
- you need text extraction, thumbnails, and OCR for mixed document formats
- you want a friendly web UI for searching and tagging local files instead of raw grep/find
- you prefer a no-dependency SQLite backend or already run Elasticsearch
- you want to schedule and manage scan jobs through a Docker-deployed admin panel

## When to avoid
- you only need quick one-off grep-like searches without maintaining an index
- you need enterprise-grade search cluster features, security, or multi-tenancy beyond what sist2 provides
- you are uncomfortable with a project the author flags as in early development, where formats and APIs may change
- your files live mostly in cloud services rather than a local or mounted file system
