Query Filters

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?"

  So notes across multiple vaults cannot be search at the same time
