优化-在Mongoose MongoDB模式中的所有字段上查找

Question

We needed to challenge our database approach and need your help

We needed to search a word/phrase in all fields of a Mongoose schema.

Let's say the schema is like this:

var sampleSchema = new Schema({
    fieldABC: String,
    fieldDEF: String,
    fieldGHI: String
});

We need to write a find query which will search for a word in all fields in a document of the collection:

db.sampleCollection.find({
  $or: [{
    fieldABC: "wordToSearch"
  }, {
    fieldDEF: "wordToSearch"
  }, {
    fieldGHI: "wordToSearch"
  }]
})

It's possible for us to write the above query but it looks very inefficient - is there some better and faster approach to this?

In the year 2015, it was not supported , is there any change in this?

Answer 1

As suggested by @Veeram

Step 1:

Create a text index

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

Step 2:

Use the text index to search the word in concern

db.sampleCollection.find( { $text: { $search: "wordToSearch" } })
