* Semantic Search
/Allow natural language search on user content like notes, images, transactions using transformer based models/
All search is done locally. User can interface with semantic-search app via [[./src/interface/emacs/semantic-search.el][Emacs]], API or Commandline
** Setup
*** Setup using Docker
**** 1. Clone Repository
#+begin_src shell
git clone https://github.com/debanjum/semantic-search && cd semantic-search
#+end_src
**** 2. Configure
- Add Content Directories for Semantic Search to Docker-Compose
- Update [[./docker-compose.yml][docker-compose.yml]] to mount your images, org-mode notes, ledger/beancount directories
- If required, edit config settings in [[./docker_sample_config.yml][docker_sample_config.yml]].
**** 3. Run
#+begin_src shell
docker-compose up -d
#+end_src
***** Troubleshooting
- The first run will take time. Let it run, it's mostly not hung
- Symptom: Errors out with "Killed" in error message
- Fix: Increase RAM available to Docker Containers in Docker Settings
- Refer: [[https://stackoverflow.com/a/50770267][StackOverflow Solution]], [[https://docs.docker.com/desktop/mac/#resources][Configure Resources on Docker for Mac]]
- Symptom: Errors out complaining about Tensors mismatch, null etc
- Mitigation: Delete content-type > image section from docker_sample_config.yml
*** Setup on Local Machine
**** 1. Install Dependencies
1. Install Python3 [Required[
2. [[https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html][Install Conda]] [Required]
3. Install Exiftool [Optional]
#+begin_src shell
sudo apt-get -y install libimage-exiftool-perl
#+end_src
**** 2. Install Semantic Search
#+begin_src shell
git clone https://github.com/debanjum/semantic-search && cd semantic-search
conda env create -f environment.yml
conda activate semantic-search
#+end_src
**** 3. Configure
- Configure files/directories to search in ~content-type~ section of ~sample_config.yml~
- To run application on test data, update file paths containing ~/data/~ to ~tests/data/~ in ~sample_config.yml~
- Example replace ~/data/notes/*.org~ with ~tests/data/notes/*.org~
**** 4. Run
Load ML model, generate embeddings and expose API to query notes, images, transactions etc specified in config YAML
#+begin_src shell
python3 -m src.main -c=sample_config.yml -vv
#+end_src
** Use
- *Semantic Search via Emacs*
- [[https://github.com/debanjum/semantic-search/tree/master/src/interface/emacs#installation][Install]] [[./src/interface/emacs/semantic-search.el][semantic-search.el]]
- Run ~M-x semantic-search <user-query>~
- *Semantic Search via API*
- Query: ~GET~ [[http://localhost:8000/search?q=%22what%20is%20the%20meaning%20of%20life%22][http://localhost:8000/search?q="What is the meaning of life"&t=notes]]
- Regenerate Embeddings: ~GET~ [[http://localhost:8000/regenerate][http://localhost:8000/regenerate]]
- [[http://localhost:8000/docs][Semantic Search API Docs]]
- *UI to Edit Config*
- [[https://localhost:8000/ui][Config UI]]
** Upgrade
*** On Docker
#+begin_src shell
docker-compose build
#+end_src
*** On Local Machine
#+begin_src shell
cd semantic-search
git pull origin master
conda deactivate semantic-search
conda env update -f environment.yml
conda activate semantic-search
#+end_src
** Miscellaneous
- The experimental /chat API endpoint uses the [[https://openai.com/api/][OpenAI API]]
- It is disabled by default
- To use it add your ~openai-api-key~ to config.yml
