MaterialSearch is a fully offline, local media search engine that uses CLIP (Chinese-CLIP) to search photos and videos by natural language or image similarity. The repository contains the frontend web application and a desktop GUI launcher; the core search logic (scanning, embedding, matching) lives in a separate, obfuscated pip package (`materialsearch-core`). The frontend is a Vue 3 single-page application built with Element Plus, providing five search modes (text-to-image, image-to-image, text-to-video, image-to-video, text-image similarity), along with file path copying, clipboard image paste, and video clip download. Deployment options include a Docker container (via docker-compose.yml) or a Windows executable bundle. The system is designed to run entirely on the user's machine with no data uploaded to the cloud, making it suitable for privacy-sensitive or air-gapped environments.
