MongoDB Evaluation Query Operators Example

Date: 2018-02-23

This tutorial explains MongoDB's evaluation query operators: $mod, $regex, $where, and $text. $mod filters documents based on the remainder after division (e.g., finding ages divisible by 5). $regex uses regular expressions for pattern matching in strings (e.g., finding names starting with "A"). $where allows JavaScript expression filtering. $text performs text searches on text-indexed fields. The tutorial provides examples and error handling for each operator.
