Reload all but one section

[gfpacheco]

The first section of my collection view has a search bar in it, and I want the rest of the collection to be updated when the user types in something.

Problem: every time the user inputs one letter, the keyboard is dismissed because the collection view reloads

Is there a way to not reload one section (maybe using reloadSections) when using RxDataSources? Or do I have to implement the delegate and data source manually?
