Comparison operators

This page details the available comparison operators when writing rules as part of the search route.

= (Equal)​

The = operator checks exact matches of the specified value:

{
  "operator": "=",
  "property": "myProperty",
  "value": "myExactValue"
}

This operator can also be used to check the value of boolean properties:

{
  "operator": "=",
  "property": "myBooleanProperty",
  "value": true
}

!= (Not Equal)​

The != operator checks exact matches of the specified value and returns all results that fail to satisfy the check:

{
  "operator": "!=",
  "property": "myProperty",
  "value": "myExactValue"
}

This operator can also be used to check the value of boolean properties:

{
  "operator": "!=",
  "property": "myBooleanProperty",
  "value": false
}

> (Greater Than)​

The > operator checks values larger than the specified value:

{
  "operator": ">",
  "property": "myNumericProperty",
  "value": 7
}

>= (Greater Than or Equal)​

The >= operator checks values larger than or equal to the specified value:

{
  "operator": ">=",
  "property": "myNumericProperty",
  "value": 7
}

< (Less Than)​

The < operator checks values less than the specified value:

{
  "operator": "<",
  "property": "myNumericProperty",
  "value": 7
}

<= (Less Than or Equal)​

The <= operator checks values less than or equal to the specified value:

{
  "operator": "<=",
  "property": "myNumericProperty",
  "value": 7
}

isEmpty​

The isEmpty operator checks if the value of the specified property is null:

{
  "operator": "isEmpty",
  "property": "myProperty"
}

isNotEmpty​

The isNotEmpty operator checks if the value of the specified property is not null:

{
  "operator": "isNotEmpty",
  "property": "myProperty"
}

propertySchema​

The propertySchema filter can be used with any standard operator. It allows you to filter entities based on a properties matching a specific type (for example, find all string properties with a given value):

{
  "propertySchema": {
    "type": "string"
  },
  "operator": "=",
  "value": "My value"
}
tip
  • The propertySchema can be used with any Port property;
  • The propertySchema replaces the property filter when performing property schema search.

between​

The between operator checks datetime values and returns entities whose relevant datetime property matches the given range:

{
  "operator": "between",
  "property": "$createdAt",
  "value": {
    "preset": "lastWeek"
  }
}

Available Presets:

  • tomorrow
  • today
  • yesterday
  • lastWeek
  • last2Weeks
  • lastMonth
  • last3Months
  • last6Months
  • last12Months

The between operator also supports standard date ranges:

{
  "combinator": "and",
  "rules": [
    {
      "operator": "between",
      "property": "$createdAt",
      "value": {
        "from": "2022-07-26T16:38:06.839Z",
        "to": "2022-07-29T17:00:28.006Z"
      }
    }
  ]
}

notBetween​

The notBetween operator checks datetime values and returns entities whose relevant datetime property does not match the given range:

{
  "operator": "notBetween",
  "property": "$createdAt",
  "value": {
    "preset": "lastWeek"
  }
}

contains​

The contains operator checks if the specified substring exists in the specified property:

{
  "operator": "contains",
  "property": "myStringProperty",
  "value": "mySubString"
}

doesNotContains​

The contains operator checks if the specified value does not exists in the specified property:

{
  "operator": "doesNotContains",
  "property": "myStringProperty",
  "value": "otherValue"
}

containsAny​

The containsAny operator checks if any of the specified strings exist in the target array:

{
  "operator": "containsAny",
  "property": "myArrayProperty",
  "value": ["Value1", "Value2", ...]
}

beginsWith​

The beginsWith operator checks if the specified property starts with the specified value**

{
  "operator": "beginsWith",
  "property": "myStringProperty",
  "value": "myString"
}

doesNotBeginsWith​

The doesNotBeginsWith operator checks if the specified property does not start with the specified value

{
  "operator": "doesNotBeginsWith",
  "property": "myStringProperty",
  "value": "otherValue"
}

endsWith​

The endsWith operator checks if the specified property ends with the specified value

{
  "operator": "endsWith",
  "property": "myStringProperty",
  "value": "myString"
}

doesNotEndsWith​

The doesNotEndsWith operator checks if the specified property does not end with the specified value

{
  "operator": "doesNotEndsWith",
  "property": "myStringProperty",
  "value": "otherValue"
}

in​

The in operator checks if a string property is equal to one or more specified string values:

{
  "property": "myStringProperty",
  "operator": "in",
  "value": ["Value1", "Value2"]
}
