Across various pages on the MoEngage dashboard, events, event attributes, and user attributes filters can be used to get to the desired analysis or segment users. To get the right analysis and the right set of users, it’s very important to know the filters. This article explains how these filters work and if there are any different behaviors or filters on different pages.

Data Types

On the MoEngage dashboard, there are seven primary data types:

String: A string is a sequence of characters. Strings are typically used to represent words and text. Character in a string can be a letter of some alphabet, a digit, a punctuation mark, a blank space, etc.
Boolean: The Boolean data type can have values as true and false.
Numeric : A number is a sequence of digits . Numeric data types are typically used to represent amount, quantity , and price.
Geo Location: Geo-location represents the location on the map using latitude and longitude.
Date Time: Date time data types represent the date and time for an event or action.
Array: An array is a group of elements. In MoEngage, we have 2 array data types: String Array and Numeric array.
Object: The Object data type provides a structured way to identify and query multiple related attributes contained within a single object. These attributes can be of any primitive data type, such as string, numeric, or date, and can be nested up to two levels. For more information, refer to Object Data Type in Segmentation.

Terms to know

Term	Description
Key	The key is a record in the database.
Key is set	The field which holds the value of an attribute.
Key not set	The field is not present to hold the value of the attribute.
Stored Value	User Behavior or User Property value that is stored in the MoEngage Application. For example, App/Site Opened, Last Seen, Email Clicked. For more information, refer to Derived Events & Attributes.
Filter Value	The value you choose to filter is based on the selected stored value. For example, you can choose the filter at least and type or select the duration or number of times the App/Site is opened.

String Filters

Operator	Explanation
is	The stored value matches one of the filter values.
exists	The stored value is present. This includes all values, including Empty String and N/A. Filter users or events where the stored value exists (Key is set).
contains	The stored value contains one of the filter values.
contains spaces	The stored value contains spaces. The spaces can be at the start, in between, or at the end of the value. This includes all values, including Empty String and N/A. Filter users or events where the stored value contains spaces. Note: The contains spaces filter will be highly relevant in the case of unique identifier (UID) attributes like ID, Mobile number, Email ID, MoEngage ID, etc. It is also highly relevant for String and Array of string data types. Other data types do not have relevant use cases and might not yield expected results.
starts with	The stored value starts with one of the filter values.
ends with	The stored value ends with one of the filter values.
is not	The stored value is not a match to any of the filter values. The Filter is applied to all the attribute’s values, including those that are not available (The Key is not set).
does not exist	The stored value is not present. The filter is applied to all the attribute values, including those that are not available (The Key is not set).
does not contain	The stored values are not a partial match to (do not contain) any of the filter values. The filter is applied to all the values in the stored attribute, including those that are unavailable (The Key is not set).
does not start with	The stored value does not start with any of the filter values. (Key not set) The filter is applied to all the attribute values, including those that are not available (The Key is not set).
does not end with	The stored value does not end with any of the filter values. The filter is applied to all the attribute values, including those that are not available (The Key is not set).
is empty	The stored value is "" (The Key is set and the value is null).
is not empty	The stored value is not "" (the stored value is not null), whether the Key is set or not.

Boolean Filters

Operator	Explanation
is	The stored value is an exact match with the filter value.
is not	The stored value does not match the filter value. The stored value includes the attributes where the value does not exist (Key is not set).
exists	The stored value is present. This includes all values, including Empty Boolean and N/A.
does not exist	The stored value is not present (The Key is not set).

Numeric Filters

For the table below - N, N1, and N2 are numeric, and N2 > N1.

Operator	Explanation
is equal to	The stored value is a match with one of the filter values.
is not equal to	The stored value does not match any of the filter values. The filter is applied to all the attribute values, including those that are not available (The Key is not set).
is between	The stored value is a match between the first filter value and the second filter value. N1 <= Stored value AND Stored value < N2. N1 & N2 are the first and second filter values, respectively.
is not between	The stored value is not matched between the first and second filter values. N1 > stored value OR stored value >= N2. N1 & N2 are the first and second filter values, respectively.
is less than	The stored value is less than the filter value. Stored value < Filter value
is greater than	The stored value is greater than the filter value. Stored value > Filter value
exists	The stored value is present. This includes all values, including Empty Numeric and N/A. Filter users or events where the stored value exists (Key is set).
does not exist	The stored value is not present. The filter is applied to all the attribute values, including those that are not available (The Key is not set).

Event Occurrence Filters

Consider the following assumptions:

Number of times user executes or does not execute the event: n
Event in consideration: Viewed Product
Today’s Date - Dec 14th 2023.
Event Retention Period for Segmentation - 30 days ( Nov 14th 2023)

Operator	Explanation
exactly	The user has the event exactly for the specified number of times. Example: Has Executed Viewed Product exactly 2 times This filter would fetch users who have viewed a product exactly twice in the specified date range added in the filter criteria.
at least	The user has executed the event at least n times (>= n) Example: Has Executed Viewed Product at least 1 times This filter would fetch users who have viewed a product at least once in the specified date range added in the filter criteria.
at most	The user has executed the event at most n times (<= n). Example: Has Executed Viewed Product at most 4 times This filter would fetch users who have viewed a product at most four times (<=4) in the specified date range added in the filter criteria.
for the first time	The user has executed the event for the first time within the specified date range. Example: Has Executed Viewed Product for the first time in the last 4 days This filter would fetch users who have viewed a product for the first time in the last 4 days(till 10th Dec 2023) and have not viewed a product before that (has not executed viewed product before 10th Dec 2023 (period in consideration here - 14th Nov 2023 to 10th Dec 2023). Note: This operator will run as per the events data retention applicable to your Workspace.
for the last time	The user has executed the event for the last time within the specified date range. Example: Has Executed Viewed Product for the last time This filter would fetch users who have viewed a product for the last time in the specified date range added in the filter criteria. Note: This operator will run as per the events data retention applicable to your Workspace.

Location-Triggered Filters

Operator	Explanation
Point with Radius	The stored geolocation value is within the circle defined by the point and the radius.

Date Time Filters

To understand filter operators in date-time data types, we need to first understand a few functions -

now = current timestamp up to milliseconds
start_of_day(timestamp) = 00:00:00 of the selected day/date
end_of_day(timestamp) = 23:59:59 of the selected day/date
n days = n * 24 hours
For the table below - n, n1, and n2 are numeric and n2 > n1.

For example

Let’s assume now is 7:30:05 PM, 5 Jan 2001 then
- now - 3 days = now - (3* 24) hours = 7:30:05 PM, 2 Jan 2001
- now + 3 days = now + (3* 24) hours = 7:30:05 PM, 8 Jan 2001
- start of the day (now) = 12:00:00 AM, 5 Jan 2001
- end of the day (now) = 11:59:59 PM, 5 Jan 2001
Let’s assume the date is 1 Jan 2001
- start of day (date) = 12:00:00 AM, 1 Jan 2001
- start of day (date + 1 day) = 12:00:00 AM, 2 Jan 2001
- start of day (date - 1 day) = 12:00:00 AM, 31 Dec 2000
- end of day (date) = 11:59:59 PM, 1 Jan 2001
- end of day (date + 1 day) = 11:59:59 PM, 2 Jan 2001
- end of day (date - 1 day) = 11:59:59 PM, 31 Dec 2000

All date-time filters work in the App time Zone, specified in Settings.

Special Date Filters

Special date filter filters for a specific hour, weekday, month, date of the month, and date of the year. This is useful for filtering out birthdays across years, and bill dates across months. Special date filters are available in the drop-down next to the date attributes in the User property and the User behavior section.

Operator	Text on Dashboard	Explanation
Date	Date	Filter the stored dates.
Hour of the day	Daily where the hour/s	Filter the stored dates based on their hour. Use this option to filter dates having specific hour/s e.g. 12 AM - 1 AM. Use this filter to segment all users whose movie time or yoga class time falls between 8 AM - 9 AM.
Day of the week	Weekly where the day/s	Filter the stored dates based on their weekday. Use this option to filter dates of specific weekdays e.g. Monday. Use this filter to segment all users who ordered food or booked a cab on Friday.
Day of the month	Monthly where the day/s	Filter the stored dates based on their day. Use this option to filter dates of a specific day of any month e.g. 5th. Use this filter to segment users whose monthly bill payment date or subscription renewal date is the 15th.
Month of the year	Yearly where the month/s	Filter the stored dates based on their month. Use this option for actions performed on a specific month of any year e.g. January. Use this filter to segment all users whose birthday or yearly subscription expiry is in March.
Date Month	Yearly where the date/s	Filter the stored values based on their date month combination. Use this option to filter dates having a specific date month combination e.g. 01 Feb. This can be used to filter birthdays and anniversaries e.g. segment users whose birthday or billing day is 15 Sep.

Special date filters are available only for user and event attributes where the data type is ‘date’. Special date filters are not available in the Affinity Segmentation and Analytics filter.

Array Filters

Two types of array filters are available. Array filters are not supported for:

Entire Analytics Suite
Triggers, Preference management, Conversion goals, and Personalization attributes

Array of Strings

contains	All of the stored values of the array contain all the filter values.
does not exist	The stored value is not present. The filter is applied to all the values of the attribute including the values that are not available (The Key is not set).
(any of) contains	One of the stored values of the array contains the filter value.
(all of) contains	All of the stored value contains filter value
does not contain	All of the stored value does not contain filter value. The filter is applied to all the values of the attribute including the values that are not available (The Key is not set).
(any of) starts with	Any of the stored values start with the filter value.
(all of) starts with	All of the stored value starts with the filter value.
does not start with	All of the stored does not start with the filter value. The filter is applied to all the values of the attribute including the values that are not available (The Key is not set).
(any of) ends with	Any of the stored values end with the filter value.
(all of) ends with	All of the stored value ends with the filter value.
does not end with	All of the stored does not end with the filter value. The filter is applied to all the values of the attribute including the values that are not available (The Key is not set).

Array of Numbers

Description for array filters for numeric values -

Filter Name	Explanation
(any of) is equal to	Any of the stored values is an exact match for at least one of the filter values.
(all of) is equal to	Stored values are an exact match for all the filter values.

contains	The stored value contains one of the filter values.
does not exist	The stored value is not present in the filter value (Key not set).

Attribute Comparison

You can now compare a user attribute to another user attribute or a constant value.
The following table lists the filters and data types supporting attribute comparison:

Data Type	Filters supporting attribute comparison
String	is, is not
Boolean	is, is not
Date	On, before, after, in the next, in the last Note: MoEngage only matches the date and not the exact time stamp for date data types.
Number	is equal to, is not equal to, is greater than, is less than
Array of Strings	(any of) is, (all of) is, is not, (any of) contains, (all of) contains, does not contain, (any of) starts with, (all of) starts with, does not start with, (any of) ends with, (all of) ends with, does not end with
Array of Numbers	(any of) is equal to, (all of) is equal to, is not equal to, (any of) is less than, (all of) is less than, (any of) is greater than, (all of) is greater than

Attribute to Attribute Comparison

You can now compare a user attribute of a specific data type with another user attribute of the same data type. Example 1: Consider a marketer looking to identify users who haven’t used their app since installing it. Comparing the First Seen and Last Seen user attributes of users can help the marketer identify the users who haven’t been active on the app since installation.

Example 2: Consider a bank entity looking to identify customers with outstanding loans. For every customer, outstanding_loan_amount and loan_amount_paid_till_date are user attributes that represent the total loan amount disbursed and the total loan amount paid by the customer to date. To identify the segment of users with an outstanding loan, the bank can compare these user attributes, as in the following example.

Attribute to Constant Value Comparison

You can now compare a user attribute to a predefined constant value. Example 1: Consider an E-commerce business looking to identify users who have spent more than $1000 on their platform while upgrading the app. The user attribute total_amount_for_upgrade represents the total amount each user has spent to upgrade the platform to date. To segment users into ‘high spenders’, the E-commerce business can compare this user attribute with a constant value of 1000 as shown below:

Limitations

The following features currently do not support the new segmentation filters (first/last seen, contains spaces, is empty/not empty, and user attribute comparison):

Conversion Goal
Business Event
Smart Trigger & Dynamic Condition
Flows

Though the new filters are not available in the above features, custom segments employing the new filters can still be created from the Create segment page and used in the features described above. In the upcoming phases, we will plan to support new filters for all the features in the dashboard.

Frequently Asked Questions (FAQs)

What is the difference between "Is Empty" and "Does Not Exist"?

The difference is between a missing field and a blank value.

Does Not Exist: The attribute key was never created or tracked for the user (for example, a “Loyalty_ID” field is completely missing from User A’s profile).
Is Empty: The attribute key exists on the profile, but the value stored is an empty string (for example, User B has a “Loyalty_ID” field, but it contains no text: "").

What's the best way to find accurate users who have a specific attribute with an actual, non-empty value?

To ensure you target users with genuine data, you should always combine the Exists and Is Not Empty operators using AND logic. This prevents the system from accidentally including users who simply don’t have the attribute at all.

Example: To find users with a valid phone number, use: (Phone Number EXISTS) AND (Phone Number IS NOT EMPTY)
Why this works: Exists confirms the field is on the profile, and Is Not Empty ensures that the field isn’t just a blank string.
