The team has placed Search for the List App on the backlog. We will share an update as soon as one is available. In the meantime, you may want to try using filter as a workaround.

The search functionality was there and I created a list and gave people instructions on how to search on it only for MS to ow remove the search functionality unless you open in SharePoint. There's no point having lists in Teams if you have to open SharePoint to use it effectively. Who takes away a function as fundamental and basic as search??
