$search (aggregation stage)

$search aggregation pipeline stage performs a full-text search of the field or fields in an Atlas collection. The fields must be covered by a MongoDB Search index.

For example, you can use $search to perform the following types of operations:

• Searches to match text fields with various patterns.
• Fuzzy matches to find terms with spelling variations.
• Compound queries to combine multiple search conditions.
• Relevance scoring to rank results.
• Return snippets of matching text.
• Vector searches to find documents using vector similarities.
