Operators

The $search aggregation pipeline stage has the following operators:

Operator	Description
autocomplete	Performs a search-as-you-type query from an incomplete input string.
compound	Combines other operators into a single query.
equals	Works in conjunction with the boolean and objectId data types.
exists	Tests for the presence of a specified field.
geoShape	Queries for values with specified geo shapes.
geoWithin	Queries for points within specified geographic shapes.
near	Queries for values near a specified number, date, or geo point.
phrase	Searches documents for terms in an order similar to the query.
queryString	Supports querying a combination of indexed fields and values.
range	Queries for values within a specific numeric or date range.
regex	Interprets the `query` field as a regular expression.
search	Deprecated. Performs analyzed search. Use text operator instead.
span	Specifies relative positional requirements for query predicates within specified regions of a text field.
term	Deprecated. Performs unanalyzed search.
text	Performs textual analyzed search.
wildcard	Supports special characters in the query string that can match any character.

Collectors

Collectors return a document representing the metadata results, typically an aggregation over the matching search results.

The Atlas Search aggregation pipeline stage has the following collector:

Operator	Description
facet	Groups query results by values or ranges in specified, faceted fields and returns the count for each of those groups. Note Preview Atlas Search facet and count are in preview, but can be used in production applications. If there are any syntax or behavior changes between the preview stage and general availability (GA), we will proactively communicate before introducing any breaking changes. The MongoDB Cloud Support team will help troubleshoot any issues related to using this feature as part of your contract.
