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](https://amplitude.com/docs/analytics/segments/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](https://en.wikipedia.org/wiki/Glob_%28programming%29).

  - 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.
