<pre>
A filter expression that matches resources returned in the response.
The expression must specify the field name, a comparison
operator, and the value that you want to use for filtering. The value
must be a string, a number, or a boolean. The comparison operator
must be `=`, `!=`, `&gt;`, or `&lt;`.

For example, if you are filtering a list of network policies, you can
exclude the ones named `example-policy` by specifying
`name != "example-policy"`.

To filter on multiple expressions, provide each separate expression within
parentheses. For example:
```
(name = "example-policy")
(createTime &gt; "2021-04-12T08:15:10.40Z")
```

By default, each expression is an `AND` expression. However, you
can include `AND` and `OR` expressions explicitly.
For example:
```
(name = "example-policy-1") AND
(createTime &gt; "2021-04-12T08:15:10.40Z") OR
(name = "example-policy-2")
```

@param value The bytes for filter to set.
