eq( )

Refines a filter to match items whose specified field value equals the specified value.

The eq() method refines this filter to only match items where the value of the specified field equals the specified value.

It only matches values of the same type. For example, a number value stored as a String type does not match the same number stored as a Number type.

Matching strings with eq() is case sensitive, so "text" is not equal to "Text".

If field points to a collection field of type array, eq() includes the item as long as at least one array element matches the specified value.
