* Emacs Khoj
  /An Emacs interface for [[https://github.com/khoj-ai/khoj][khoj]]/

** Requirements
   - Install and Run [[https://github.com/khoj-ai/khoj][khoj]]

** Installation
*** Direct
     - Put ~khoj.el~ in your Emacs load path. For e.g ~/.emacs.d/lisp
     - Load via ~use-package~ in your ~/.emacs.d/init.el or .emacs file by adding below snippet
       #+begin_src elisp
         ;; Khoj Package
         (use-package khoj
           :load-path "~/.emacs.d/lisp/khoj.el"
           :bind ("C-c s" . 'khoj))
       #+end_src

*** Using [[https://github.com/quelpa/quelpa#installation][Quelpa]]
     - Ensure [[https://github.com/quelpa/quelpa#installation][Quelpa]], [[https://github.com/quelpa/quelpa-use-package#installation][quelpa-use-package]] are installed
     - Add below snippet to your ~/.emacs.d/init.el or .emacs config file and execute it.
       #+begin_src elisp
         ;; Khoj Package
         (use-package khoj
           :quelpa (khoj :fetcher url :url "https://raw.githubusercontent.com/khoj-ai/khoj/master/interface/emacs/khoj.el")
           :bind ("C-c s" . 'khoj))
       #+end_src

** Usage
   1. Call ~khoj~ using keybinding ~C-c s~ or ~M-x khoj~
   2. Enter Query in Natural Language
      e.g "What is the meaning of life?" "What are my life goals?"
   3. Wait for results
      *Note: It takes about 15s on a Mac M1 and a ~100K lines corpus of org-mode files*
   4. (Optional) Narrow down results further
      Include/Exclude specific words from results by adding to query
      e.g "What is the meaning of life? -god +none"
