Syntax conventions	Description
Lowercase and uppercase	Literal keyword. Includes `()`.
`Italics`	Variable value. Replace with a user-defined value.
`[]`	Optional. Square brackets ( `[]` ) surround optional command arguments. Do not type the square brackets.
`{}`	Group. Braces ( `{}` ) identify a group to choose from. Do not type the braces.
`\|`	Or. A vertical bar ( `\|` ) separates alternative elements. Type any one of the elements. Do not type the vertical bar.
`...`	Repeatable. An ellipsis ( `...` ) indicates that you can repeat the syntax element as often as required.

The is() step is a filter step that is used to filter for scalar values.

g.V().
   where(__.hasLabel('meal_item').values('calories').is(lte(1200))).
   values('name', 'calories')

Note that this example could be accomplished with a has() step.

But this example could not be accomplished with a has() step:

g.V().hasLabel('meal').filter(out('includes').values('calories').sum().is(gte(1000)))
