Query operators

Graph traversal ($edge)
All employees of a company Finds Innovate Inc. and returns all its Employee descendants.
All active developers Two conditions in the sub-query: every descendant must match both.
Nested traversal A company, then a Developer descendant, then that developer's descendant named Bob.
Employees 38 or older in Data Corp The starting point is narrowed by name; the operator filters its descendants.
Employees tagged JavaScript $in against an array field, applied to the descendants.
Descendants matching either role A logical operator inside $edge: the sub-query is a full query, so $or applies to the descendants rather than to the starting point.
No matching descendants The companies exist and are found, but nothing below them is a Contractor: a traversal that matches nothing returns an empty result, never the starting node.
Conditional operators
$eq — name is "Alice" Finds the employee with that exact name.
$gte — age 35 or older Also $gt, $lt and $lte, with the same shape.
$between — age from 30 to 40 Both ends included, given as a two-element array.
$in — level is Senior or Lead Matches a field against a list of accepted values.
$exists — has an email address Asks whether the field is there at all, whatever its value.
Logical operators
$and — developer and from the USA Every clause must match.
$or — inactive or older than 40 Any clause matching is enough.
$not — country is not the USA Wraps another operator and inverts it.
Text search
$regex — name starts with B A regular expression, anchored with ^.
$regex — name contains "an" Unanchored, so it matches anywhere in the value.
Natural language (nlq module)
Nested traversal, in English The same query as "Nested traversal" above, written as a sentence.
Company → descendant named Bob Without naming a type or a role for the descendant.
Finds only companies The simplest prompt there is: one type, no filters.
Descendant developers A traversal with no explicit starting point.
Nested traversal with order and limit Type, role, name, ordering and a ceiling — all in one sentence.
$or and $and, in English Developer or Designer, and from the USA.
A list of accepted values Parses to $in.
Starts with, ordered and capped Name starts with B, ascending by name, first ten.
Ends with The mirror of the previous one.
SQL-style like Recognised too: name like "J%".
Between, ordered and capped Age from 30 to 40, ascending, first five.
Between two dates ISO dates in a range, ordered by the same field.
Traversal into an array field "includes" reaches inside the tags array.
Negation Parses to $not.
Full text search Across the fields of every node, rather than one named field.
Full text search, lowercase Same result: the search is case-insensitive.
First two employees by name Ordering and limit with no filter at all.
