$searchBeta¶

Atlas Search queries take the form of an aggregation pipeline stage. The $searchBeta stage performs a full-text search on the specified field or fields which must be covered by an Atlas Search index.

A $searchBeta pipeline stage has the following prototype form:

copy

{
  $searchBeta: {
    <operator>: {
      <specification(s)>
    }
  }
}

Behavior¶

The $searchBeta stage has the following operators:

Operator	Description
