At the heart of MongoDB lies its versatile query language, designed to retrieve, manipulate, and analyze data stored in its document-oriented format. The query language's syntax is intuitive, making it accessible to both beginners and experienced developers.
- Basic Querying: To retrieve documents from a collection, you use the `find()` method. It allows you to filter documents based on specific criteria. For instance:
“javascript
db.products.find({ category: "electronics" })
“
- Comparative Operators: MongoDB provides a range of comparison operators like `$eq`, `$gt`, `$lt`, `$gte`, and `$lte`. These operators help you refine queries by comparing field values.
“javascript
db.orders.find({ totalAmount: { $gt: 1000 } })
“
- Logical Operators: Logical operators like `$and`, `$or`, and `$not` allow you to combine conditions for complex queries.
“javascript
db.customers.find({ $or: [{ age: { $lt: 25 } }, { age: { $gte: 60 } }] })
“
- Array Operators: MongoDB efficiently handles arrays with operators such as `$elemMatch` and `$size`, enabling targeted searches within arrays.
“javascript
db.posts.find({ comments: { $elemMatch: { author: "Alice", score: { $gte: 5 } } } })
“
- Text Search: The `$text` operator enables full-text search, helping you find documents that contain specific keywords.
“javascript
db.articles.find({ $text: { $search: "MongoDB query language" } })
“
