2. Similar to example 1, shown below are two equality matchers combined in a short form YAML list. 2. Similar to example 1, shown below are two equality matchers combined in a short form YAML list.
```yaml ```yaml
matchers: [ "foo = bar", "dings != bums" ] matchers: [ foo = bar, dings != bums ]
``` ```
As shown below, in the short-form, it's generally better to quote the list elements to avoid problems with special characters like commas: As shown below, in the short-form, it's generally better to quote the list elements to avoid problems with special characters like commas:

3. You can also put both matchers into one PromQL-like string. Single quotes for the whole string work best here. 3. You can also put both matchers into one PromQL-like string. Single quotes for the whole string work best here.

4. To avoid any confusion about YAML string quoting and escaping, you can use YAML block quoting and then only worry about the OpenMetrics escaping inside the block. A complex example with a regular expression and different quotes inside the label value is shown below: 4.
