MongoDB Text Search In Aggregation Pipeline
We can search text using the aggregation pipeline with the help of the $text query operator in the $match stage. But there are some restrictions for using the $text operator:
- The first stage in the pipeline must be the $match stage that contains the $text operator.
- Only once in the stage will a text operator occur.
- The expression of the text operator cannot appear in expressions of $or or $not.
- By default, the text search does not return matching documents in the order of the matched scores. If you want to sort in descending score, then use the $meta aggregation expression in the $sort stage.
Note: Text score is a score that is assigned to each document that holds the search term in the index field by the $text operator. The score reflects a document’s importance to a given text search query.
