Hi @Adhil_E and welcome to MongoDB the community forum!!

Based on the sample data provided above, I created the index in the following way:

{
  "mappings": {
    "dynamic": true,
    "fields": {
      "company.name": {
        "type": "string"
      }
    }
  }
}

and the following search query returned me the above documents:

db.newAtlasS.aggregate(db.newAtlasS.aggregate([
  {
    $search: {
      index: 'default',
      text: {
        query: 'bbbb',
        path: 'company.name'
      }
    }
  }
]
)

Output for which is:

[
  {
    _id: ObjectId("63864d60959925ab51e0cf96"),
    name: 'abcd',
    price: '21',
    test: 'aaa',
    company: { name: 'bbbb' }
  }
]

For more detailed information, please refer to the documentation on nested field search.
