Assign Weights To Each Field While Creating An Index In Mongodb

In this article, we will assign weights to each field while creating an index in MongoDB.

The weight assigned to an indexed field indicates its importance relative to other indexed fields when calculating the text search score.

   { weights: { [field1]: [weight1], [field2]: [weight2], ... } }
)

Consider the following document: -

To assign the weight while creating an index, we will use the following query: -

db.products.createIndex(
   { name: "text", address: "text" },
   { weights: { name: 5, address: 1 } }
);
