Custom. guide- message spotlight search in channel/s

[vanGalilea]

Motivation A lot of our customers are asking how they can build a message search functionality in a spec. channel or in all channels.

Proposed solution Write a custom. guide on how to achieve this spotlight search func.

Acceptance Criteria A custom. guide is published and includes all relevant code snippets, screenshots, and desc. steps. The guide will cover similar func. that we already have in our sample app.
