I always get weird search results when searching branches for file changes.
When I select a branch, select the Search tab and switch to File Changes I get the following outcomes:

• Even though a newer commit is available, I only get older ones (commited today, but result list starts with a commit from 6 days ago and backwards)
• Some results do not even include the file I am searching for and none of the files in the commit or any of the text changes in that file contain my search string
• searching for a concrete file with extension (.cs) does not list any commits at all
