### Interface
![](https://github.com/debanjum/khoj/blob/master/src/interface/obsidian/docs/khoj_obsidian_screenshot_0.1.0.png)

## Setup
### 1. Setup Backend

```shell
pip install khoj-assistant && khoj --no-gui
```
### 2. Setup Plugin
  1. Open *Community plugins* tab in Obsidian settings panel
  2. Click Browse and Search for *Khoj*
  3. Click *Install*, after that click *Enable* on the Khoj plugin

See [official docs](https://help.obsidian.md/Advanced+topics/Community+plugins#Discover+and+install+community+plugins) for details

## Use
Click the *Khoj search* icon 🔎 on the [Ribbon](https://help.obsidian.md/User+interface/Workspace/Ribbon) or Search for *Khoj: Search* in the [Command Palette](https://help.obsidian.md/Plugins/Command+palette)

<details><summary>Query Filters</summary>

Use structured query syntax to filter the natural language search results
- **Word Filter**: Get entries that include/exclude a specified term
  - Entries that contain term_to_include: `+"term_to_include"`
  - Entries that contain term_to_exclude: `-"term_to_exclude"`
- **Date Filter**: Get entries containing dates in YYYY-MM-DD format from specified date (range)
  - Entries from April 1st 1984: `dt:"1984-04-01"`
  - Entries after March 31st 1984: `dt>="1984-04-01"`
  - Entries before April 2nd 1984 : `dt<="1984-04-01"`
- **File Filter**: Get entries from a specified file
  - Entries from incoming.org file: `file:"incoming.org"`
- Combined Example
  - `what is the meaning of life? file:"1984.org" dt>="1984-01-01" dt<="1985-01-01" -"big" -"brother"`
  - Adds all filters to the natural language query. It should return entries
    - from the file *1984.org*
    - containing dates from the year *1984*
    - excluding words *"big"* and *"brother"*
    - that best match the natural language query *"what is the meaning of life?"*

## Upgrade
### 1. Upgrade Backend
  ```shell
  pip install --upgrade khoj-assistant
  ```
### 2. Upgrade Plugin
  1. Open *Community plugins* tab in Obsidian settings
  2. Click the *Check for updates* button
  3. Click the *Update* button next to Khoj, if available

## Troubleshooting

  2. Toggle Enable/Disable Khoj, in case settings changes have not applied
  3. Click *Update* button to force index to refresh if results are failing or stale

## Current Limitations
- The plugin loads index of only one vault at a time.<br/>
  So notes across multiple vaults **cannot** be search at the same time

## Implementation
The plugin implements the following functionality to search your notes with Khoj:
- [X] Open the Khoj search modal via left ribbon icon or the *Khoj: Search* command
- [X] Render results as Markdown preview to improve readability
- [X] Configure Khoj via the plugin setting tab on the settings page
  - Set Obsidian Vault to Index with Khoj. Defaults to all markdown files in current Vault
  - Set URL of Khoj backend
  - Set Number of Search Results to show in Search Modal
- [X] Allow user to trigger reranking of result to improve search quality
