Men’s Men’s Stripe Men’s Dark Sweater Red Stripe Sweater Dark Red or condition A or condition B
and condition A and condition B

{% if product.type == "Shirt" or product.type == "Shoes" %}
  This is a shirt or a shoe.
{% endif %}


contains checks for the presence of a substring in a string.

contains can also check for the presence of a string in an array of strings.

Men’s Men’s Sweater Dark Red Men’s Stripe Red Stripe Dark Sweater {% if product.tags contains "outdoor" %}
  This product is great for using outdoors!
{% endif %}

contains can only search strings. You cannot use it to check for an object in an array of objects.

Dark Red Stripe Sweater Men’s Sweater Red Men’s Dark Men’s Stripe 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 Dark Red Stripe Red Sweater Men’s Men’s Stripe Dark Men’s Sweater and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andSweater Stripe Stripe Red Red Sweater Men’s Men’s Men’s Dark Dark 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
{% endif %}
