# \$1eq
<a name="eq"></a>

The `$eq` operator in Amazon DocumentDB is used to match documents where the value of a field is equal to the specified value. This operator is commonly used in the `find()` method to retrieve documents that meet the specified criteria.

**Parameters**
+ `field` : The field to check for the equality condition.
+ `value` : The value to compare against the field.

## Example (MongoDB Shell)
<a name="eq-examples"></a>

The following example demonstrates the usage of the `$eq` operator to find all documents where the `name` field is equal to `"Thai Curry Palace"`.

**Create sample documents**

```
db.restaurants.insertMany([
  { name: "Thai Curry Palace", cuisine: "Thai", features: ["Private Dining"] },
  { name: "Italian Bistro", cuisine: "Italian", features: ["Outdoor Seating"] },
  { name: "Mexican Grill", cuisine: "Mexican", features: ["Takeout"] }
]);
```

**Query example**

```
db.restaurants.find({ name: { $eq: "Thai Curry Palace" } });
```

**Output**

```
{ "_id" : ObjectId("68ee586f916df9d39f3d9414"), "name" : "Thai Curry Palace", "cuisine" : "Thai", "features" : [ "Private Dining" ] }
```
