Documentation: How to change DataSearch value from outside?

**Affected Projects**
React, but maybe all

**Describe the solution you'd like**
Would it be possible to have an example on how to set DataSearch value from external JS code keeping it uncontrolled (if it's possible) and another one with a DataSearch controlled by App.

**Additional context**
Sometime we have full external script (like get the current calling number/IP from a switch) and pass it as a search value or a filter. This action being link to a button.

By the way, congratulations for this project!

Start with the DataSearch documentation and its React component API. Add examples showing how external JavaScript can set the search value while keeping DataSearch uncontrolled, and how an App can control DataSearch; done when both requested usage patterns are documented.
