Sportswear Men's Nike Shorts Nike Sportswear Shorts Modern Men's Modern Order of operations

In tags with more than one and or or operator, operators are checked in order from right to left. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.

{% if true or false Nike Shorts Sportswear Sportswear Modern Men's Men's Modern Shorts Nike and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andShorts Sportswear Modern Men's Nike Nike Sportswear Men's Modern Shorts false and false or true %}
  This evaluates to false, since the tags are checked like this:

  true and (false and (false or true))
  true and (false and true)
  true and false
  false
{% endif %}
