# Analytics filters and segments

> Filter every dashboard report by source, page, country, event or property, combine conditions with AND and OR groups, and save them as reusable segments.

## Filters

Click any row in a panel to add an `is` filter (Alt/⌥-click for `is not`),
or use **+ Filter** (`F`) to build one: choose a dimension, an operator and
one or more values. Active filters show as chips. Click a chip to change
it, **Clear** (`Esc`) to remove them all.

Filters apply to every metric, chart and panel on the page, and are kept
in the URL.

### Operators

| Operator | Meaning |
|---|---|
| `is` / `is_not` | Equals / doesn't equal |
| `any_of` / `none_of` | Equals one of a list / none of a list |
| `contains` / `not_contains` | Substring match, case-insensitive |
| `starts_with` | Prefix match |
| `regex` / `not_regex` | Regular expression (up to 200 characters) |
| `gt`, `lt`, `between` | Numbers, for numeric properties |

### AND and OR

Separate filters are combined with **AND**. Put conditions in an OR group
to match any of them: "channel is Email **or** utm_medium is newsletter".
Up to 20 conditions in total.

### What a filter selects

- **Visit dimensions** (source, channel, UTM, country, device, browser,
  entry page…) select visits.
- **Page** selects visits that viewed the page, and pageview counts for
  that page.
- **Event**, **goal** and **property** filters select visits in which that
  event or goal happened.

The full list of dimensions and the JSON syntax used in URLs and the API
are in [Filters (API)](/docs/api/filters).

## Segments

A segment is a saved set of filters with a name, like "Paid traffic from
the US" or "Visits that saw pricing". Choose one with the **Segment**
picker (`S`). It combines with any filters you add on top.

Create one with **+ New segment**, or save the current filters. Segments
belong to the site and are shared with everyone who can see it. Use them in
the API with `segment_id=seg_…`.
