As boolean (As BOOLEAN) operator

The AS BOOLEAN (or AS BOOL) operator is used to cast an operand to a boolean. Depending on the type of operand, the casting will work as:

operand type	Rule
String	Will be true if the value is yes, true, y, ort (case insensitive)
Boolean	Will return the value as is.
Date	Will return true.
Number	Will return true if the number is not zero (0).
Path	Will return true if the file exists
List	Will return true if the list is not empty
Class	Will return true if the class is not empty
Empty	Will return Empty

For example:

findit -w 'content.take(1) AS BOOLEAN'

Will show all the files that starts with y, Y, t, or T
