Updated 2 months ago

scout is a RESTful search server written in Python. The search is powered by SQLite's full-text search extension, and the web application utilizes the Flask framework.

Scout aims to be a lightweight, RESTful search server in the spirit of ElasticSearch, powered by the SQLite full-text search extension. In addition to search, Scout can be used as a document database, supporting complex filtering operations. Arbitrary files can be attached to documents and downloaded through the REST API.

Scout is simple to use, simple to deploy and just works.

Features:

  • Multiple search indexes present in a single database.
  • RESTful design for easy indexing and searching.
  • Simple key-based authentication (optional).
  • Lightweight, low resource utilization, minimal setup required.
  • Store search content and arbitrary metadata.
  • Multiple result ranking algorithms, porter stemmer.
  • Besides full-text search, perform complex filtering based on metadata values.
  • Comprehensive unit-tests.
  • Supports SQLite FTS4.
  • Documentation hosted on ReadTheDocs.
