Segment operators

Amplitude segment filters use operators to evaluate property values, user behavior, and sessions. This reference lists the operators for each filter type. For how to add filters, refer to Create segments.

Property operators

Property filters support these operators:

• is or is not: Include or exclude exact property values.
• contains or does not contain: Include or exclude property values that contain a substring. These operators aren't case sensitive.
• starts with or does not start with: Include or exclude property values that start with a prefix. These operators aren't case sensitive.
• set is or set is not: Include or exclude an exact array set. For example, Interests {=} Movies, Music matches only when the array contains exactly Movies and Music. An array with only Movies doesn't match, and an array with Sports, Movies, and Music doesn't match.
• set contains or set does not contain: Match arrays that contain all the selected values, or that don't contain all the selected values. Use these operators to find users who belong to multiple A/B test groups.
  • To exclude certain values from a property array, use set does not contain.
  • With multiple values, these operators apply AND to the values. For example, with set does not contain group A and group B, a user must be in neither group A nor group B to qualify for exclusion. To apply OR, use multiple set does not contain filters.
• glob match or glob does not match: Match or exclude strings with a simple pattern syntax, like /org/*/chart/*, where * is a wildcard. Patterns like *[0-9] and [!a-z]* match values that end in a digit and values that start with a non-letter, respectively. For more information, refer to the Wikipedia article on glob patterns.
  • A single asterisk matches only non-/ characters. To match strings that contain /, use two asterisks. For example, to match all URLs in the format www.example.com/blogs/blog_id that contain the word "blog", use glob match with **blog**.

Multiple values

When you select multiple values in one operator, Amplitude applies OR to the values. For example, Country is United Kingdom, Japan matches events from the United Kingdom or Japan.

set is and set is not are the exception. These operators require an exact match on the entire set, so they don't apply OR to multiple values.

Users who performed operators

Users who performed filters support these operators:

• count: The number of times a user triggered the event. For example, users who triggered Favorite Song or Video more than five times in the last 30 days.
• distinct property count: The number of distinct values of a property for the selected event.
• in each: Includes users who meet the event condition in each chart interval. For example, at least three downloads per week qualifies users separately for each week.
• during: Includes events triggered in the date range you choose. Use a fixed range between two dates or a rolling range like Last 30 Days.
• since: Includes events triggered since the date you choose.
• within: Includes events triggered within a set number of days of each user's first use.

Session operators

Sessions filters support these operators:

• contains event: Includes only sessions with at least one event that matches the conditions you set.
• with property: Filters sessions by the first or last non-null value of a property in the session. For example, use the first or last value of Page Path to filter to entry or exit pages. To filter on a property value at any point in the session, use contains event, select Any Event, then add the property filter.
• duration: Filters sessions by length, for example, sessions longer than 30 seconds or shorter than 5 minutes.
