MongoDB Drop Index in Example

Specify weights
For a text index, the weight of an indexed field is the significance of the field. In MongoDB, for each index field in the document, MongoDB sums the results by multiplying the number of matches by weight. Now using this sum, MongoDB calculates the score for the document. The default weight of the index field is 1 and you can adjust the weight of the index using createIndex() method.
Example:
db.studentsposts.createIndex({title:"text", tags:"text"},
{weights:{title:10, tags:5},
name:"TextIndex"})
Here, the weight of the title and tags field is 10 and 5.
