> Blue Fabric Red and Strong Check Cotton greater than
< less than
>= greater than or equal to

Blue Strong Cotton Check Fabric and Red or condition A or condition B

{% if product.type == "Shirt" or product.type == "Shoes" %}

{% endif %}

contains

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

Fabric Cotton Blue Red Check Strong and {% if customer.email contains "shopify.com" %}
  Hey there, Shopify employee!
{% endif %}

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

Cotton and Check Blue Fabric Strong Red {% 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.

Fabric and Check Red Cotton Strong Blue 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 Red Fabric Strong Check Blue and Cotton and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andRed and Cotton Fabric Strong Blue Check 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 %}
