+
+h3. Filters
+
+The value of the @filters@ parameter is an array of conditions. The @list@ method returns only the resources that satisfy all of the given conditions. In other words, the conjunction @AND@ is implicit.
+
+Each condition is expressed as an array with three elements: @[attribute, operator, operand]@.

+|0|attribute|string|Name of the attribute to compare|@script_version@, @head_uuid@|
+|1|operator|string|Comparison operator|@>@, @>=@, @like@, @not in@|
+|2|operand|string, array, or null|Value to compare with the resource attribute|@"d00220fb%"@, @"1234"@, @["foo","bar"]@, @nil@|
+
+The following operators are available.
