Boolean Logic and Using Subqueries/Boolean Order of Operations

Boolean Searching


Use Boolean operators AND, OR, and NOT to specify inclusions, alternate terms, or exclusions (You can substitute AND, OR, and NOT with &&, ||, and ! respectively). Keywords and field searches can be separated by any of the above in order to fine-tune your results.
  • drugs OR crime – find documents with either 'drugs' or 'crime'
  • drugs AND crime – find documents with both 'drugs' and 'crime'
  • DarkOwl AND (hack OR ddos OR 0day) – find documents with DarkOwl and any one of three hacking keywords

Boolean operators must be in all caps. If they are not in all caps, DarkOwl Vision will consider the word "and", "or", etc as keywords.

Using Subqueries/Boolean Order of Operations

You can group together phrases to form subqueries, using parentheses ( ) to indicate each clause. This is especially important when both ANDs and ORs are used, to designate the correct order of operations for your subqueries.

  • DarkOwl AND (drugs OR crime) – find documents with DarkOwl and either drugs or crime
  • ("AES-256" OR "AES 256") AND ("RSA-4096" OR "RSA 4096") – find documents with one of AES-256 or AES 256 and one of RSA-4096 or RSA 4096
