All data is processed locally. User can interface with semantic-search app via Emacs, API or Commandline

Dependencies

• Python3
• Miniconda

Install

git clone https://github.com/debanjum/semantic-search && cd semantic-search
conda env create -f environment.yml
conda activate semantic-search

Run

python3 main.py --input-files ~/Notes/Schedule.org ~/Notes/Incoming.org --verbose

Use

• Semantic Search via Emacs

  • Install semantic-search.el
  • Run M-x semantic-search <user-query> or Call C-c C-s

• Semantic Search via API

  • Query: GET http://localhost:8000/search?q="What is the meaning of life"
  • Regenerate Embeddings: GET http://localhost:8000/regenerate
  • Semantic Search API Docs
