Yes, it is. Examples:

• for a title >= 50 characters
  

  title:"~^.{50}"

  The regex says "starting at the beginning of the item (the ^), match if there are 50 or more of any character (the .{50}".
• for a title < 50 characters
  

  not title:"~^.{50}"

The technique works for multi-value columns like tags and authors, checking each value.
