project the score

Fix this Playground so that the score being projected is the relevancy score Atlas Search uses for default sorting.

Solution

The score is available in the pipeline $meta context as searchScore.

{"$meta": "searchScore"}

Enable the score details and project them into the results.

Solution

Enable the score details with this setting in $search:

scoreDetails: true

Include the score details by adding this to $addFields:

"scoreDetails": {
  "$meta": "searchScoreDetails"
}

Set the search (relevance) score to the value of the weight field.

Solution

Use the weight value as the score for the compound operator:

"score": {
  "function": {
    "path": "weight"
  }
}
