This document is a quick reference for query operators you can use to query anything that's on your content objects.

To experiment with querying your content from within Builder, you can use the Builder API Explorer.

This document covers the following operators:

Comparison Operators

$eq

$gt

$gte

$in

$lt

$lte

$ne

$nin

Logical Operators

$and

$not

$or

$nor

Element Operators

$exists

$type

Array Operators

$elemMatch

Evaluation Operators

$regex

$options

MongoDB style queries for your Builder data

When querying Builder data, you can use MongoDB style operators, such as:

Operator	Description
`$eq`	Use to match values equal to a specified value.
`$gt`	Use to match values greater than a specified value.
`$gte`	Use to match values greater than or equal to a specified value.
`$in`	Use to match any of the values you specify in an array.
`$lt`	Use to match values less than a specified value.
`$lte`	Use to match values that are less than or equal to a specified value.
`$ne`	Use to match all values not equal to a specified value.
`$nin`	Use to match none of the values specified in an array. This example excludes the numbers `50` and `51`.
`$and`	Use to join query clauses with a logical `and` and return all documents that match the conditions of both clauses.
`$not`	Use to invert the effect of a query expression and return documents that do not match the query expression.
`$or`	Use to join query clauses with a logical `or` and return all documents that match the conditions of either clause.
`$nor`	Use to join query clauses with a logical `nor` and return all documents that do not match both clauses.
`$exists`	Use to match documents that have the specified field.
`$type`	Use to select documents if a field is of the specified type.
`$elemMatch`	Use to select documents if element in the array field matches all the specified `$elemMatch` conditions.
`$regex`	Use to select documents where values match a specified regular expression.
`$options`	Use to specify options to use with `$regex`. For more detail about available options, refer to the MongoDB `$regex` documentation.
