mongo $text {$search: "something"}

Question

Trying to make searching in mongo using a part of the word that stored in the document

getCitiesWithQuery(reqQuery) {
    let query = {$text: {$search: reqQuery}};
    return db.collection('cities').find(query).toArray();
}

But I`ve got this error:

MongoError: text index required for $text query

How to fix it?

Answer 1

You need to create text index on that collection first. This example code below indexes every field that contains string data for each document in the collection

db.cities.createIndex(
   { "$**": "text" }
 )

Answer 2

By definition, $text looks for words only. If you're using MongoDB Atlas, you can make use of Atlas Search , which allows for partial searching (and fuzzy matching and other things).
