Use

Search

See Khoj Search for details

1. Hit C-c s s (or M-x khoj RET s) to open khoj search
2. Enter your query in natural language

E.g. "What is the meaning of life?", "My life goals for 2023"

Find Similar Entries

This feature finds entries similar to the one you are currently on.

1. Move cursor to the org-mode entry, markdown section or text paragraph you want to find similar entries for
2. Hit C-c s f (or M-x khoj RET f) to find similar entries

Advanced Usage

• Add query filters during search to narrow down results further e.g. What is the meaning of life? -"god" +"none" dt>"last week"

• Use C-c C-o 2 to open the current result at cursor in its source org file

  • This calls M-x org-open-at-point on the current entry and opens the second link in the entry.
  • The second link is the entries org-id, if set, or the heading text. The first link is the line number of the entry in the source file. This link is less robust to file changes.
  • Note: If you have speed keys enabled, o 2 will also work

• Hit t until you preferred content type is selected in the khoj menu Content Type specifies the content to perform Search, Update or Find Similar actions on
