[New Feature] Add a search functionality

[mohsenkhosroanjam]

Description: As a user, I can add reminders in the application.

Actual result: There is no search functionality. If I want to find a specific reminder, I have to scroll and search by eyes.

Expected result: There should be a search functionality that searches through reminders that have been added. As a result, if the user searches for something, the result should be shown consequently.

Steps to reproduce: 1- Add some reminders
